Extract values of TN, FP, TP and FN stata

[ashraf abugroun]

Dear Stata exper,
Wonder how to extract values of TN, FP, TP and FN into seperate variables in stata
For example following logistic regression to predict a binary outcome using a score value, I know these variables are generated for ROC curve for model accuracy, but i want them to be seperately retained in my var list, so as i can apply them in further tests like midas package.
appreciate help
Thanks

Type return list after you run estat classification. You'll see a list of scalars. These are like temporary variables stored in memory that aren't part of your dataset. You can, however, save them as permanent scalars or as actual variables, e.g.

gen false_positive = r(P_p0)

Note the description of the scalars in the estat classification manual (see Stored Results).
