In one of my lectures about distributions, I was taught that in QQ-plot all points should be within z=+/-2 !, If we have such a definition we should be able
to calculate p-value for QQ plot, right? visual assessment of qqplot is very subjective !
Is that possible to create QQ plot in stata for multivariate normality (like in R), for example using "mvtest normality" (default is dhansen test).
thanks so much
