Specification of the Outlier Univariate Model

N. P. Olewuezi

Abstract

Problem statement: An outlier is an observation that deviates so much from other observations so as to arouse suspicion that it was generated by a different mechanism. Approach: In this study, outlier univariate model was specified based on statistical measures, Outlier Free (OF) and Outlier Contaminated (OC) models were Stated and compared. Results: The number of expected outliers obtained and the effect of the presence of outliers were noted. Conclusion: The outlier univariate model incorporated the modeling change in an evolving extension.
