st: stcox: bootstrap option produces LOWER standard error and WIDER ci95
Dear Statalist members, I apologize for this reposting. For some reason I
have been unsubscribed for several days. Here's my question:
I'm using stcox to estimate survival with one binary covariate (tcm), with
Perhaps I'm mistaken, but I was expecting the bootstrap option to produce
a higher standard error and wider ci95.
BOOTSTRAP MODEL HR CI95 SE p
NO tcm 0.77 0.36, 1.67 0.30 0.51
YES tcm 0.77 0.39, 1.55 0.27 0.47
Can anybody suggest why that might be the case?
