How to make (using only the menu) TWO ROC-curves in the same plot (for comparison their)?

Sample three variables are:

T (temperature),

status (0-not sick, 1-sick).

age (1-young, 2-old).

We need give two ROC-curves (for young and old groups) on the same plot.

Did you try copying the contents of one FrameBox to another?

1. Right click on the white area of the 'source' ROC and select 'Edit > Copy Frame Contents'.
2. Move to the 'target' ROC, right click on the white area and select 'Edit > Paste Frame Contents'.

Ian's method is what I do.  I also use the customize menu (right click "Customize...") to change the colors of the curves.  Once you select the Customize you will  get a dialog box.  On the left is list and for a ROC curve in that list will be a couple of items called "Script".  The first might look like:

Pen Color( 9 );

Y Function( XTemp + 0.511242728306672, XTemp );

I will often delete that one as it is what draws the "yellow" line on the ROC curve that I am generally not interested in. The second will start like:

Line(

[0, 0.0007097232079489, 0.0014194464158978, 0.0014194464158978,

0.0014194464158978,

If you click on the "Templates" menu and select "Pen Color" you will get

Pen Color("blue");Line(

[0, 0.0007097232079489,

Then you can change the color to any color you want (use a color word with the quotes or use a # without the quotes, I usually just pick a word: red, green, purple, orange, etc.).

Dear Karen, Many Thanks for the detailed answer! I'll try!

Amazing! Many thanks, Ian!!!

So a little after the fact - I knew there was a way to do the multiple ROC curves without the copy frame contents - I just couldn't remember where at the time.  So,

1. Save your models to your data table

2 . Modeling>model compare

3. Select the models and click Y, Predictors, click OK

4. In the model compare red triangle select ROC and done.
