how do I adjust decimals in PWCORR

[chenzitian]

I know some options like corrtab mkcorr allow adjustment of decimals, but I also need stars for significance. Thanks!

Concerning pwcorr you should simply do what the help for pwcorr says: Use the sig and star options:

sysuse auto, clear
pwcorr price headroom mpg displacement, sig star(0.05)

I need to only keep two decimals in pwcorr, which doesn't seem to allow it.

You can help yourself and could save the pairwise correlations in a matrix which elements are rounded to two decimals.

sysuse auto, clear
corr price mpg headroom
matrix A = r(C)
matrix C = J(3, 3, 0)
forvalues i=1/3 {
    forvalues j=1/3 {
        matrix C[`i',`j']= round(A[`i',`j'], 0.01)    
    }
}
matrix list C

To add significance levels you could run univariate regressions for each pair and save the p-value of the Ftail(1, e(N), e(F)). If you further wish to add stars for the significance levels -- what seems redundant given that you already state p-values, you can work with if/else statements in the loop.
