Ok, I guess my real question was the difference between CINTERVAL(BOOTSTRAP) and CINTERVAL(BCBOOTSTRAP) - unlike SYMMETRIC, both seem to take the distributionof the bootstrap into account. Beyond taking the distribution into account what does bias-correction do? As a rule, wouldn't someone always want bias corrected bootstrap?
I believe this has been fixed. Are you using Version 4.1? If not, I suggest you download it. If you have the same problem in Version 4.1, you should send your input, output, and data to firstname.lastname@example.org.
