Since bootstrapping works by selecting random samples of the dataset the results will be different each time. But if you have enough bootstrap replications, then the results shouldn't differ much. To get exactly the same results, you should set the seed for the random number generator to the same positive integer each time:
set seed 27
bootstrap ...
_bootstrap_ is the more up-to-date name than _bstrap_ for the command.

I'm using bstrap to estiamte the bias of ATT using psmatch and I getting
differente results each time I run it. Why is this? Is this normal? is any
way to replicate the results?
