Precision Recall curves in Stata

[Naz Av]

Hi all, for those of you familiar with Receiver Operating Characteristic (ROC) Curves in Stata: is there a user written program for Precision Recall (PR ) curves?

I know how the PR curve differs from the ROC curve so theoretically one would modify the roctab or other associated Roc ado files to generate the area under the curve (AUC). However, I lack the programming knowledge to undertake this endeavor.
Any tips?

The command "prtab" is now on Boston College Statistical Software Components (SSC) and can be installed by typing "SSC install prtab" in Stata.

This command's primary purpose is plotting precision-recall curves, but can also plot precision as a function of threshold or rank and plot the F-score as a function of the threshold. Please contact the author (email is provided in the help file) if there are any other features that you would like.

on this topic, does STATA calculate a confidence interval for PR curves as well?
