Hi statalists!
When does one need to correct the skewness of an independent variable? I have a logit regression and my indep variable is strongly skewed; do I need to correct this (by using lnskew0 )??
I tried to correct my variable, but Stata gave this error message (see below); what does it mean? why it gave this message?
lnskew0 lnindepvar = indepvar
invalid matrix stripe;
.z_
r(198);
