st: Bootstrap with some samples ill-conditioned

["Jun Xu" <mystata@hotmail.com>]

Dear all,

I have a question re bootstrap predicted probability in order logit. I have 
an ordinal dependent variable with four categories with one category having 
insufficient cases. I have a bootstrap routine to sample with replacement 
and estimate teh model, but sometime, the sample does not contain that 
category in the dependent variable. How to adjust for that? Should I just 
ignore it when calculating the bootstrap average and the percential (or 
normal) confidence intervals? Could you suggest some quick reference into 
this problem? Really appreciate.
