Testing Normality assumption in Linear regression in STATA

Описание: Normality of error terms is one of the key assumptions of linear regression, especially for valid hypothesis testing and confidence intervals. In this video, I demonstrate how to test the normality of residuals in STATA using both graphical methods (histogram, Q-Q plots) and Shapiro-Wilk test
