Thresholds displayed on ROC Curve

[Grace Heymsfield]

I'm graphing a binary variable on a 7-category variable, and I'd like the 7 categories to be labeled on the plot- any advice? I'm using the following code, then graph Editor.

roctab SAMWHZ GAMMUAC_severity, binomial detail table graph summary

Your points on the bottom left-hand corner are so clumped up together, it is hard to see how the labels will be legible. Here is a way to do it (highlighted)

sysuse auto, clear
lab define rep78 1 "Poor"  2 "Fair" 3 "Average" 4 "Good" 5 "Excellent"
lab values rep78 rep78
decode rep78, gen(labels)
roctab foreign rep78, binomial detail table graph summary plotopts(mlab(labels)) xsc(r(. 1.1))

In your case, decode GAMMUAC_Severity. If labels overlap, look at

help marker_label_options

for possible remedies. If nothing helps, you can insert the labels manually using the text option within plotopts().
