Model Quality: Residuals

Because models can have low or high R-square while fitting the data very poorly, it is important to document that the residuals are normally distributed with uniform variance. This is also documented using the standardized and studentized residual plots for each of the final models.  The LD and LEMR residual plots can be contrasted against the original residual plots from Gelb and Mizokawas' regression analyses.

LD, standardized residual plot and studentized residual plot.

LEMR, standardized residual plot and studentized residual plot

LSED, standardized residual plot and studentized residual plot
