Re: st: tobit?
Have you tried all the transformations in -gladder-?

Quoting Mona Mowafi <[email protected]>:
Dear statalisters,
I have a dataset in which I am evaluating the effect of SES on BMI
and BMI is heavily skewed toward obesity (i.e. over 50% of the
sample >30 BMI). I preferred to run a linear regression so as to
use the full range of data, but the outcome distribution violates
normality assumption and I've tried ln, log10, and sqrt
transformations, none of which work.
Is it appropriate to use tobit for modeling BMI in this instance?
If not, any suggestions?
Your insight is much appreciated.
Many thanks,
Mona
