Dear Maarten,

I hope you dont mind me privately contacting you.
I have another, Im sure a silly question.

Are you familiar with stepwise function on stata. I have a model that i 
need to
back test. Im playing around with the function, however, am not making much
progress. Your thoughts and assistance would be most appreciated.

Regards,

Bilal
