How I read these . signs in col chi2(2) in this picture?
Array
From stata instructions I have understood that I should test the smallest, in this case the log transformation. And what is the meaning of col P(chi2)? Is it the p-value? What is the hypothesis behind that p? Does this picture mean, that any of these transformations don't transform me the variable which is normally distrubuted?
Other question: is there any normality test for bigger amounts of variables? I have 6411 variable in my whole data and from stata instructions I have read:
swilk can be used with 4 < n<2000 observations. sfrancia can be used with 10<n<5000 observations; however, if the boxcox option is specified, it can be used with 5<n<1000 observations.
Many thanks if somebody can give some answers!
