The time-series Moving Average (MA) model is a nonlinear model; see, for example. For traditional Least Squares (LS) fits, there are several algorithms to use for computing its fit. Since the model is...Journal of Mathematics and Statistics, Published online: 2022-07-28; doi:10.3844/jmssp.2022.87.1002022-07-28 DOI: 10.3844/jmssp.2022.87.100
