Michael McCulloch <[email protected]>:
Not to beat a dead horse, "does not work" is uninformative. The x in
the bootstrap output tells you that whatever commands you are running
are not producing the necessary output. If you reframe your problem
using a dataset that ships with Stata or availabel via -webuse- (see
http://www.stata.com/help.cgi?streg for examples), you will get better
answers from the list. Does the program run if you just type
msmcox_stageIIIA_includeIPTWd at the command prompt? If so, type
-return list- after that one run and verify r(tcm) is returned.

Thanks Stan, the bootstrap is used for inference as it's a Marginal
Structural Models survival analysis. -noisily- does not work here,
but I really appreciate the suggestion!
Comments from others would also be greatly appreciated.
Many thanks to all,
