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;
