st: how to deal with a censored and skewed regressor?

[mbaier <melanie.baier@c-lab.de>]

Dear statalisters,

I tried to transform it according to ln(skewed variable), but my 
regressor has a lots of values at zero, for which ln is not defined. I 
also tried to create an index like I=100*(x-r(min))/(r(max)-r(min)), 
which again leads to many missings (due to many x's being zero).
What can I do?
Besides, do I have to account for the censoring of my regressor? If so, 
what can I do?

Thanks a lot,

melanie baier
