Hi,

I am relatively new on STATA, so I have some questions..I am trying to estimate a model based on a cross-section, in which the dependent variable Y is log-transformed, and the independent variable X is not. I would like to draw some conclusions about the elasticity of X. Should I use the 'eyex' command, or just to log the variable X in order to directly derive the elasticity? Generally, the most commonly applied method for deriving elasticities is the 'eyex' command?

Lastly, I am trying to use the 'eyex' command after a two-part model, but the STATA mentions

Warning: cannot perform check for estimable functions.

A retransformation method must be specified.

invalid syntax

r(198);

Could you please help me on this? How can I run the 'eyex' command after a two-part model?

Thank you very much.
