  • A Study on Determination of Outlier Observations by Using Chi-Square
           Threshold Value

    • Authors: Fahrettin Kaya; Esra Yavuz, Şeyma Koç, Ömer Faruk Karaokur
      Abstract: Outlierobservations are observations that are out of the tendency of all observationsin a data set. The observations come out in situations such as faultyobservation, incorrect data entry. It is important to be able to identify theseobservations as the results of statistical analysis, for example such asmultiple regression analysis, can be quite sensitive against to theseobservations. Outlier observations are mostly determined by using distancecalculation, statistical test and density based approaches. In this study, thedistances of each observation vector to the center were calculated withMahalanobis distance by using R program. For this purpose, the features such ashematokrit (htc), hemoglobin (hgb), mean platelet volume (mpv), plateletdistribution width (pdw), nonbacterial prostatitis (nbp) and pulse pressurevalues measured in the blood of 315 heart patients were examined as data set.As a result of the research, sixteen observations were found as outlierobservation. It is thought that the result of this study will help theresearchers trying to find out especially the outlier observations.

  • Comparison of Commonly Used Statistics Package Programs

    • Authors: Ömer Faruk Karaokur; Fahrettin Kaya, Esra Yavuz, Aysel Yenipınar
      Abstract: Thespecialized computer programs used in the collection, organization, analysis,interpretation and presentation of the data are known as statistical software.Descriptive statistics and inferential statistics are two main statisticalmethodologies in some of the software used in data analysis. Descriptivestatistics summarizes data in a sample using indices such as mean or standarddeviation. Inferential statistics draws conclusions that are subject to randomvariables such as observational errors and sampling variation. In this study,statistical software used in data analysis is examined under two main headingsas open source (free) and licensed (paid). For this purpose, 5 most commonlyused software were selected from each groups. Statistical analyzes and analysisoutputs of this selected software have been examined comparatively. As a resultof this study, the features of licensed and unlicensed programs are presentedto the researchers in a comparative way.

  • Contrast Analysis on Single Factorial Studies and Solution with SPSS

    • Authors: Demet Çanga; Aysel Yenipınar, Ömer Faruk Karaokur, Ayşe Betül Önem, Ercan Efe
      Abstract: Contrastanalysis is a method for comparing sets of means using specific coefficientsfor weighting the means. In this study, contrast analysis as a plannedcomparison method and its use in one-factor trial designs are examined. For thispurpose, a hypothetical data set is used to analyze the data related to theamount of dry matter determined by three different methods. The steps of thecontrast analysis are explained using the SPSS.18 package program. Inconclusion, contrast analysis results showed that a great part of thedifference between the methods is due to the difference between method 3 andthe others (p <0.01) according to F test detailed with 1 degree of freedom.

  • Determining Sample Size in Logistic Regression with G-Power

    • Authors: Aysel Yenipınar; Şeyma Koç, Demet Çanga, Fahrettin Kaya
      Abstract: Thereare several methods used to determine the sample size. Investigator; because ofthe insufficient precious resources such as time, labor, money, tools andequipment, it works by pulling the sample with a suitable sampling method fromthe population it is examining. According to the statistics obtained from thesample, he will make comments about the population and make decisions. Thecorrectness of the decisions made is closely related to the size of the sample.For this reason, the problem of determining sample size is one of the first andimportant problems of an investigator. A small sample of information causesloss of information and misjudgments. A very large sample is contrary to thepurpose of sampling and resources are wasted. The calculation of the samplesize can now be done very easily via free programs.

  • Modeling of Individual Growth Curves in Japanese Quails

    • Authors: Esra Yavuz; Ayşe Betül Önem, Fahrettin Kaya, Demet Çanga, Mustafa Şahin
      Abstract: Thisstudy was conducted to determine the adaptation of the individual growth curvesof Japanese quails to both female and male quail data modeled by using Richard,Logistic, Gompertz, Von Bertalanffy, Cubic Spline and Quadratic Spline models.In the study, 810 quail data consist of 298 females and 512 males were used asmaterial. For six different models, Mean Square Error (MSE), Durbin-Watsonautocorrelation test (DW), Akaike Information Criteria (AIC), AdjustedDetermination Coefficient (adj. R2)values were compared for both female and male quails. In addition modelpredictions of growth curve parameters were shown. As a result of this studyfor individual growth curve models in Japanese quails, MSE= 92.50 ± 17.69,adj.R2=0.986 ± 0.001, AIC= -19.21 ± 0.15 and DW= 2.21 ± 0.01 forfemale quails MSE= 35,391 ± 9.07, adj.R2=0.997 ± 0.033, AIC= -35.04 ± 0.29 and DW= 2.09 ± 0.91 for male quail. It was found the cubic Splinemodel, which was the best model for both female and male quails.

  • Evaluation of Some Body Dimensions with Cronbach Alpha Coefficient in
           Saanen Kids

    • Authors: Ebru Ergüneş Berkin
      Abstract: Cronbach'salpha coefficient (α), which was developed by Cronbach (1951), is an internalconsistency estimation method, and still remains the most widely used measureof scale reliability. Although reliability analysis is mostly used in thesocial sciences, in this study it is applied to some body measurements for 82head of Saanen kids at third months of age. The independent variables weredetermined as X=(x1, x2, x3, x4); the withers height (x1=WH), body length(x2=BL), chest depth (x3=CD), rump height (x4=RH). As the dependent variable,sixth month live weight (Y=LW) was taken. Thus, by calculating, it is aimed toinvestigate whether the explanatory variables constitutes to explain ahomogeneous structure in whole. The total  for 4 independent variables is calculated as 0,900. On the other hand,since the coefficient of CD variable was calculated as 0.908. This variable wasexcluded from the analysis because of decreasing the reliability. As a resultof the reliability analysis, decreasing the number of variables decreased theR2 value and increased the Mean Square Error (MSE). According to this; The R2value for the 4 variables is 75.80% and for the 3 variables 69.50% which islover. In this study, it was determined that the reliability of the variable hadno effect on the model. This may be due to the nature of the data. As a result,3 independent variables were found to confirm that they form a wholeexplanation for a homogeneous structure.

  • The Present of Scrapie and the Result of Breeding Program in Europe and
           Cyprus

    • Authors: Meryem Betmezoğlu; Dilek Arsoy
      Abstract: Scrapieis a fatal neuro-degenerative disease of sheep and goats belongs to the groupof transmissible spongiform encephalopathy (TSEs). Classical scrapie resistanceand susceptibility are closely related to PrP Gene polymorphism (ARR, ARQ, VRQ,and AHQ ARH) in sheep. The ARR / ARR genotype is the most resistant. Subsequentannual testing campaigns among the animals at risk were done in Europe from2001 to 2015 showed that the goat had at least 16 silent mutation of a specificstudy of PrP distribution. In 2014, the test in sheep and goats carried outunder the frame work of the TSE monitoring programs in E.U showed that 1.015out 325.530 sheep and 1.437 out of 127.016 goats turned out positive to classicalScrapie. There are Scrapie cases reported in both south and north Cyprus.Infected herds in Southern Cyprus represent 22.6% (2014) of total active sheepand goat herds. It has been also known that there are Scrapie cases in NorthernCyprus although there is no official data recorded. Some sheep breeds have thehighest ARR / ARR allele like Canadian Arcott with 39.3%, Dorset Down with28.9%, and Polypay with 26.8%. Among the sheep breeds, the Chios has thehighest level of ARR allele with 38% in Turkey and 32.5% in North Cyprus whilethe lowest level (5.9%) was seen in Awassi in Turkey. In the TSE eradicationprogram applied in Europe (2015): 1.When BSE cannot be excluded, all animals> 18 months killed for destruction shall be tested for TSE.2. When TSE andatypical Scrapie can be excluded, option A; Killing and complete destruction orslaughter for human consumption (SHC) of all animals. Option B: Killing andcomplete destruction of the susceptible animals only. Option C: No mandatorykilling and complete destruction of animals. In Europe, selected male animalswhich have ARR / ARR gene are used in breeding program. As a result of thebreeding programs implemented in Europe; 1108 Scrapie cases reported in 2002decreased to 685 in 2016.
