st: Multiple nonlinear equations regression with categorical variables

[John Kim <tiderunner00@hotmail.com>]

Hi,

I'm a complete newbie to Stata and I wanted to see if there 
is a built-in command in Stata that would be appropriate for my needs. Some of my colleagues who heard about my issue told 
me that Stata may have what I am looking for but I don't own the program 
and wanted to ask for more opinions before I purchase the program.

I
 
have one dependent variable (continuous) that I would like to explain 
with five independent variables. Four of them are continuous and one is 
categorical. I am looking for a model that would allow me to fit 
different
 nonlinear (exponential, logarithmic) as well as linear equations to 
each of the continuous independent variables. I am also interested in 
testing some of
 the interaction terms in the same model, most notably between the 
categorical and the continuous independent variables. Is there a Stata 
command that 
would allow me to do this? Ideally, the model would also provide some 
indication of which main and interaction terms should be included for 
greatest parsimony.

Any help or leads would be greatly appreciated. Thanks for your consideration.
