  • Asymmetrical triadic relationship based on the structural difficulty
    • Authors: Koji E. Kosugi
      Abstract: Abstract Using Bayesian inference, this study aims to estimate the magnitude of the cognitive load when a person perceives asymmetric social relations. Some empirical evidence relating to balance theory has shown that a balanced state is comparatively easier to memorize than an unbalanced one. In this study, since a balanced state is defined by structural complexity, an experimental hypothesis was set whereby asymmetric social relationships have different difficulty levels depending on structural complexity. The balanced state of an asymmetric relation as structural difficulty is formally derived from the eigenvalue structure of a Hermitian matrix. Asymmetric triadic relations are modeled as featuring three kinds of structural difficulties according to the eigenvalue decomposition of the Hermitian matrix and pattern-specific difficulties. The differences among the structural difficulties were not sufficiently significant to exceed pattern-specific difficulties, but the Bayes factor of the informational hypothesis of this research yielded positive effects.

  • Coping with career development: a field study measuring the influence of
           work characteristics and employee personality
    • Authors: Marcus Selart; Svein Tvedt Johansen
      Abstract: Abstract This study tested a model of the relationship between work performance, employee personality, and perceived career development. The model hypothesized that employee personality (extraversion) modifies the relationship between work characteristics (task, diversity, work feedback) and perceived career development. Results revealed that work characteristics (task diversity, work feedback) was positively related to perceived career opportunities and that extraversion positively moderated the relation between work characteristics (task diversity, work feedback) and perceived career opportunities. Issues related to the common method bias are discussed (see e.g. Podsakoff et al. in J Appl Psychol 88(5):879–903, 2003).

  • Identified and unidentified cases of the fixed-effects 3- and 4-parameter
           models in item response theory
    • Authors: Haruhiko Ogasawara
      Abstract: Abstract The 3-parameter logistic (3PL) model including guessing parameters is one of the popular models in item response theory. While the guessing parameters in the fixed-effects 3PL model with non-stochastic abilities have been believed to have identification, some counter examples with new ones given in this paper are currently available. In this paper, the concept of degeneracy for nested models is introduced. Some degenerate cases in the counter examples are shown to have model identification for guessing parameters, which are further shown to have model unidentification in a more degenerate model. Similar results in the fixed-effects 4-parameter logistic model are also derived.

  • Logistic regression with misclassification in binary outcome variables: a
           method and software
    • Authors: Haiyan Liu; Zhiyong Zhang
      Abstract: Abstract Measurement error in continuous, normally distributed data is well known in the literature. Measurement error in a binary outcome variable, however, remains under-studied. Misclassification is the error in categorical data in which the observed category is different from the underlying one. In this study, we show, through a Monte Carlo simulation study, that there are non-ignorable biases in parameter estimates if the misclassification is ignored. To deal with the influence of the misclassification, we introduce a model with false-positive and false-negative misclassification parameters. Such a model can not only estimate the underlying association between the dependent and independent variables, but it also provides information on the extent of the misclassification. To estimate the model, a maximum likelihood estimation method based on a Fisher scoring algorithm is utilized. A simulation study is conducted to evaluate the performance, and a real data example is given to demonstrate the usefulness of the new model. An R package is developed to aid the application of the model.

  • Question word-order influences on covariate effects: predicting zero-sum
    • Authors: Michael Smithson; Yiyun Shou; Alice Yu
      Abstract: Abstract Zero-sum-like statements have the form “The more of resource X for consumer A, the less of resource Y for consumer B” and these have four permutations, whereby {X, A} and {B, Y} exchange places, and/or “more” and “less” exchange places. Smithson and Shou (Front Psychol 7:984, 2016) found that these permutations strongly influence the endorsement of such statements. This paper reports two studies investigating personality traits as predictors of zero-sum endorsements, and whether their predictive performance is moderated by statement permutations. Social Dominance Orientation, Competitive World View, the Egocentricity subscale from the Levenson Self-Report Psychopathy Scale, and the Interpersonal subscale from the Hare Self-Report Psychopathy Scale are shown to be positively associated with zero-sum endorsement, whereas none of the Big-5 personality factors are. Only the Egocentricity subscale’s effect is moderated by statement permutations, so that for high scores on the subscale, zero-sum endorsement is boosted in such a way that the permutation effects disappear. The paper concludes with a discussion of the methodological implications of attitude statement permutation effects.

  • How previous choice affects decision attribute weights: a field survey
    • Authors: Tsuyoshi Hatori; Satoshi Fujii; Kazuhisa Takemura
      Abstract: Abstract The objective of this study was to examine the effects of people’s prior choice making on their weights of decision attributes. According to theories on post-decision processes, preferences are likely to be reconstructed in line with a preceding choice. The present study hypothesized that preferences are constructed so that superior (inferior) attributes of a chosen alternative are weighted higher (lower) than before. This hypothesis was tested in a field survey of university students in Japan. The data supported the hypothesis that the weights of the superior (inferior) attributes of the chosen alternative increased (decreased) as time passed since the decision was made. This result suggests the validity of the causal relationship in which choice shapes preference, which is the reverse of what is generally assumed in decision research.

  • Diverse reports recommendation system based on latent Dirichlet allocation
    • Authors: Masaki Uto; Sébastien Louvigné; Yoshihiro Kato; Takatoshi Ishii; Yoshimitsu Miyazawa
      Abstract: Abstract This paper presents a proposal for system supporting learners in improving their report-writing skills by recommending reports from previous learners. The proposed system recommends reports that share similar subjects but which have different structures, expressions, and originality based on the distributions of words and subjects within the reports, as estimated using latent Dirichlet allocation (LDA). An important assumption made for this study is that reports with different word distributions tend to include different structures, expressions, and originality when they share similar subjects. Based on that assumption, the system selects and recommends reports that have dissimilar word distributions but which share similar subject distributions with a learner’s report. The proposed system is expected to enhance learning of various writing skills from other learners. Finally, this paper demonstrates the effectiveness of the proposed system through actual data experiments.

  • Respondents with low motivation tend to choose middle category: survey
           questions on happiness in Japan
    • Authors: Shinya Masuda; Takayuki Sakagami; Hideaki Kawabata; Nobuhiko Kijima; Takahiro Hoshino
      Abstract: Abstract Some studies have shown low proportions of Japanese people rating their lives as happy. However, most surveys in Japan revealed that response distributions for subjective well-being items indicated excessive blips in middle categories. In this study, participants responded to four items that were designed to detect careless or unmotivated respondents; these items instructed respondents to choose a certain response category. Of the study’s respondents, about 40% failed to follow instructions for at least one of the four items. Besides, they often chose middle categories for well-being items. When those who did not follow instructions were excluded from the complete sample, middle categories showed low or no blips, and the proportion of respondents with high rating scores increased. Thus, this study suggested that one reason for reportedly low proportions of happy people in Japan was respondents who were not diligent in reading items.

  • A note on large-scale logistic prediction: using an approximate graphical
           model to deal with collinearity and missing data
    • Authors: Maarten Marsman; Lourens Waldorp; Gunter Maris
      Abstract: Abstract Large-scale prediction problems are often plagued by correlated predictor variables and missing observations. We consider prediction settings in which logistic regression models are used and propose a novel approach to make accurate predictions even when predictor variables are highly correlated and only partly observed. Our approach comprises three steps: first, to overcome the collinearity issue, we propose to model the joint distribution of the outcome variable and the predictor variables using the Ising network model. Second, to render the application of Ising networks feasible, we use a latent variable representation to apply a low-rank approximation to the network’s connectivity matrix. Finally, we propose an approximation to the latent variable distribution that is used in the representation to handle missing observations. We demonstrate our approach with numerical illustrations.

  • An International Research Comparative Study of the Degree of Cooperation
           between disciplines within mathematics and mathematical sciences: proposal
           and application of new indices for identifying the specialized field of
    • Authors: Yuji Mizukami; Yosuke Mizutani; Keisuke Honda; Shigenori Suzuki; Junji Nakano
      Abstract: Abstract Based on 10 years of data on academic papers from 2005 to 2014 available on the “Web of Science”, we conducted an in-depth review and analysis of collaborative academic research activities and relationships in mathematics/mathematical science and 21 other fields. We focused on the “academic papers co-authored with researchers in other fields” and derived new methods for measuring the degree of research cooperation among disciplines. Our new methods consist of two steps. The first step involves measuring and deriving new indices for identifying the specialized field of each researcher and the degree of concentration of each researcher’s work in his or her field of specialization. The second step, based on the indices, utilizes the Lorenz curve and Gini coefficient to identify the characteristics of each field. We analyzed the temporal trends in the data for 15 major countries from 2007 to 2014, to determine if the degree of cooperation between disciplines is changing. We also analyzed the characteristics of different regions: the European Union, North America, Asia without Japan, and Japan. We confirmed the effectiveness of our new methods and obtained some interesting findings that offer a new perspective on academic research activities.

  • Error asymmetry in causal and anticausal regression
    • Authors: Patrick Blöbaum; Takashi Washio; Shohei Shimizu
      Abstract: Abstract It is generally difficult to make any statements about the expected prediction error in an univariate setting without further knowledge about how the data were generated. Recent work showed that knowledge about the real underlying causal structure of a data generation process has implications for various machine learning settings. Assuming an additive noise and an independence between data generating mechanism and its input, we draw a novel connection between the intrinsic causal relationship of two variables and the expected prediction error. We formulate the theorem that the expected error of the true data generating function as prediction model is generally smaller when the effect is predicted from its cause and, on the contrary, greater when the cause is predicted from its effect. The theorem implies an asymmetry in the error depending on the prediction direction. This is further corroborated with empirical evaluations in artificial and real-world data sets.

  • Use of cognitive diagnostic model to study differential item functioning
           in accommodations
    • Authors: Dubravka Svetina; Shenghai Dai; Xiaolin Wang
      Abstract: Abstract This study explored potential sources of differential item functioning (DIF) among accommodated and nonaccommodated groups by examining skills and cognitive processes hypothesized to underlie student performance on the National Assessment for Educational Progress (NAEP). Out of 53 released NAEP items in 2007 for grade 8, a total of 25 items were flagged as DIF among the four studied groups (nonaccommodated, accommodated with extra time, accommodated with read aloud, and accommodated with small groups) by a generalized logistic regression method. The Reparameterized Unified Model was fit to the same data using a Q-matrix containing 25 skills that included content-, process-, and item-type attributes. The nonaccommodated group yielded the highest averages of attribute mastery probabilities as well as the largest proportion of mastered examinees among all the groups. The three accommodated groups tended to have similar attribute mastery means, with the group accommodated with small groups yielding a larger proportion of mastery examinees when compared to the other two accommodated groups.

  • Effectiveness of rank correlations in curvilinear relationships
    • Authors: Agostino Tarsitano; Ilaria Lucrezia Amerise
      Abstract: Abstract In cases where only linear relationships are suspected, Pearson’s correlation is generally used to measure the strength of the association between variables. It is well-known, however, that when a non-linear or non-linearizable connection exists, the use of Pearson’s coefficient on original values can be deceiving. On the other hand, rank correlations should perform satisfactorily because of their properties and versatility. There are many coefficients of rank correlation, from simple ones to complicated definitions invoking one or more special transformations. Each of these methods is sensitive to a different feature of dependence between variables The purpose of this article is to find a coefficient, if one exists, that tends to be different from zero at least in a meaningful way more often than others when the relationship between two rankings is of a non linear type. In this regard, we analyze the behavior of a few well-known rank correlation coefficients by focusing on some frequently encountered non-linear patterns. We conclude that a reasonably robust answer to the special needs arising from non-linear relationships could be given by a variant of the Fisher–Yates coefficient, which has a more marked tendency to reject the hypothesis of independence between pairs of rankings connected by several forms of non-linear interaction.

  • Approximating score distributions using mixed-multivariate beta
    • Authors: Tomoya Okubo; Shin-ichi Mayekawa
      Abstract: Abstract One approach to smoothing empirical score distributions is to apply a probability distribution. However, the score distributions sometimes form a ‘toothed’ shape, meaning that the probability distribution does not always fit well. The normal distribution can be applied for the fitting; however, this has a symmetric shape and a domain ranging from minus infinity to plus infinity. Polynomial log-linear models are often used for fitting frequency distributions, especially those with complicated shapes, but these do not provide information on the frequency distribution. In this study, we propose the maximum likelihood model for approximating a discrete distribution. Our approach is based on the mixed-multivariate beta distribution, which can cover asymmetric score distributions with known upper and lower bounds. Further, a simulation study is conducted to compare the results from the application of the mixed-multivariate beta distribution, mixed multivariate normal distribution, and two polynomial log-linear models. Results from a real data analysis are also given in this research.
