Hi All

I have a question on predict command. 

If I run a poisson regression such as

poisson absdays male black hispanic bluecollarworkers
nohealthinsurance backpain comorbidconditions

where all the independent variables are dummy
variables. 

absdays=constant + b1*male + b2*black + b3*hispanic +
b4*bluecollarworkers + b5*nohealthinsurance +
b6*backpain + b7*comorbidconditions 

If from the output only black, backpain, and
comorbidconditions were statistically significant, can
I run the predict command to obtain
the predicted number of absdays using only the
significant variables?

In otherwords can I get the predicted absdays as

constant + b2*black + b6*backpain +
b7*comorbidconditions 

I know one option is to use the generate command but I
would like to know if we can do this using predict
command too. 

Thank you for your time.

Regards
Anju
