Actually that is not correct. When using the -st-
commands, weights are specified at the time the data
is -stset-. If Monica specifies [pw=] when she stsets
her data, then all subsequent -st- commands will use
pweights. Here is a simple example:
. sysuse auto, clear
. stset mpg [pw= gear_ratio], fail( foreign)
. streg price, dist(weib)
. stcurve, at1(price=6000) surv
