ROC Table with Cutpoints

rmiller70 — Tue, 12 Sep 2017 22:49:26 GMT

I have successfully created a SAS ROC Plot and have obtained the charted output. See attached picture. However, I am trying to obtain a table identical to how STATA will output its table (See 2nd attached picture). Can anyone help guide me into how I can get SAS to output cut-points?

Thanks!

Can you show your code so far? 🙂

A good start may be in the ROCOPTIONS part of the PROC LOGISTIC Documentation specifying ID=PROB | CUTPOINT.

Check model option CTABLE, PPROB

My code for this model is:

proc logistic data=test.n;

model yes (ref = first) = score /outroc = rocscore;

roc;

run;

Can you assist with adding these model options into the following code?

proc logistic data=test.n;

model yes (ref = first) = score /outroc = rocscore;

roc;

run;

**I tried adding each after the rocscore but it wouldn't run properly.

How do I add those options onto the code that I have pasted? Thanks!

Hi . You can search these options at support.sas.com   and you will find the answer.


proc logistic data=sashelp.class;
model sex=height weight  /outroc = rocscore ctable pprob=(0.8 0.7 0.6 0.5 0.4);
run;
