Heteroskedasticity is an important issue encountered in statistics and econometric models, particularly in regression analyses. One of the fundamental assumptions of the classical linear regression model is that the error terms have constant variance (homoskedasticity). If the variance of the error terms is not constant—that is, if variance varies across observations—this condition is called heteroskedasticity. Theoretical Background Under the assumption of constant variance, the variance of the
