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.
