how to display covariance - correlation matrix from a logistic regression model

[Tara Boyle]

Hello I'm looking to display the cholesky covariance - correlation matrix from a logistic model

pwcorr mpg price rep78

//attempt 2

reg price mpg foreign
matrix cv=cholesky(e(V))

error: matrix not positive definite r(506); Then I attempted to use - matselrc (Stata Journal; Nick Cox) However, apparetnyl this has been marked as historical What is the alternative ?

worked for me, but I'm running the latest version.

sometimes, I have trouble doing things with e matrices.
try

matrix V = e(V)
matrix cv = cholesky(V)
