Like Nick says, we'll need to see the commands;
and better yet would be a reproducible
example. Here is an example of where it works fine:Dear All,
I am trying to draw a PPS sample using the "gsample" command. I want
to make sure I get the same sample each time I invoke the gsample
command by using the "set seed" command. However, even after I set the
random seed using "set seed" command, I still get different sample
each time. Has anybody encountered this problem? Thanks!
Best,
