Amal replied privately that he was familiar with -sts graph, but could
not produce 95% CIs. He can, if he adds the "ci" option:
**********************
webuse stan3, clear
label define surgery 0 "No Surgery" 1 "Surgery"
label values surgery surgery
sts graph , survival ci by(surgery) separate
**********************************
-sts- commands do not accept a -by- prefix. If Amal wishes to store
the graphs separately, he could write:
**********************
levelsof surgery, local(levels)
foreach i of local levels{
sts graph if surgery== `i', survival ci saving(gs`i', replace) ti("`:
label (surgery) `i''")
}
*********************************************************
Amal would have had an answer sooner- and saved us both a bit of
time, if he had, as the FAQ request, shown us the code he'd tried.
