Dear Statalisters,

I am writing you because I would like to find out if I have duplicate variables in my database.
I have been looking in previous posts, but I only found a recommendation about doing a pwcorr, that I think is an interesting possibility, but considering that I have almost 400 variables is going to be hard considering the large output.
If you could advice me, I really appreciate it.

Thank you so much !!
Alejandro
