computed and store chi2

Hello stata users,

Thank you for taking the time to address my concern. (and sorry for my english..).I've been looking for two hours and I don't know how to do.

I want to check out , in my descriptives statistics if there's a difference between two samples (let say users and non users )

Because my DV and IV are categorical I cannot use p-value significance. I first used used this command : 2*ttail(e(df_r),abs(_b[VARIABLE1]/_se[Variable1] in a loop and obtain a matrix of descriptives statistics with significant differences , before I realized it wasn't appropriate.

my question is how do I computed chi2 statistic instead of pvalue (2*ttail(e(df_r),abs(_b[VARIABLE1]/_se[Variable1]) in stata ? how to do it by hand like the pvalue calculation?
Is there a relationship with pvalue and chi2 so I can use the pvalue I have, to calculate chi2?


Thank you very much for your help!
