Snippet: The estimated models are not free from any misspecifications. As the diagnostic tests indicate, the estimated models are suffering from heteroscedasticity and violate the normality assumption. However, the models are free from autocorrelation (except model 1) as indicated by Breusch-Godfrey LM test statistic and high multicollinearity as indicated by high Ì… 2 and significant t-ratios for all explanatory variables.

Document: The estimated models are not free from any misspecifications. As the diagnostic tests indicate, the estimated models are suffering from heteroscedasticity and violate the normality assumption. However, the models are free from autocorrelation (except model 1) as indicated by Breusch-Godfrey LM test statistic and high multicollinearity as indicated by high Ì… 2 and significant t-ratios for all explanatory variables. Consequently, the estimated coefficients are unbiased, though do not possess minimum variances.
