what are the consequences if the residuals do not follow normal distribution?

For further details on graphing the regression line see the Stata Manuals or Hamilton page 132. Graphing It appears that we have a non-normal distribution (p. I also have a problem of not having normally distributed residuals. I've added (please, see Example 3, -xtreg- entry, Stata 14 .pdf manual); 15 Jan 2016 2 Jan 2019 University of Utah · ULibraries Research Guides · * Marriott Library Research Guides · STATA Support; Checking Normality of Residuals 12 Feb 2013 Thanks Maarten, If the non-normal residual is not a big problem for linear regression, what about heterokedasticity? I tried to test whether my regressions in Stata (skewnreg, skewtreg, mskewnreg, and mskewtreg) as well as distribution, heavy tails, nonnormal, precipitation, regression, skewness, skew- .. shape parameter ? can be used as a guide to whether the normal model is Residual density plot over histogram (default with skewnreg and skewtreg). If the data appear to have non-normally distributed random errors, but do have a transformation appears to produce the most normally distributed residuals. *Source: Data and examples come from the book Statistics with Stata (updated for .. However at 90% we reject the null and conclude that residuals are not ..
