A Probabilistic Application of Generalized Linear Model in Discrete-Time Stochastic Series

Imoh Udo Moffat & Emmanuel Alphonsus Akpan · Journal of Scientific Research and Reports · 2018

This study is aimed at identifying the problem associated with Ordinary Least Squares (OLS) in relation to the violation of assumptions of normality and constant variance. Mainly, the possible problem encountered when these assumptions are violated is the introduction of biases i...
