Which p-value are you referring to? The one for the overall fit? The test
that one of the indiividual coefficients is zero? After estimation, you can
get the overall p-value by referring to e(chi2) and e(df_m), then
calculating the p-value using the chiprob( ) function. For example, you
could do
scalar prob= chiprob(e(df_m), e(chi2))
For the individual p-values on coeficients, you can get the values and
standard errors using e(b) and e(V), then calculate the p-values yourself,
assuming a normal distribution.
