st: interpretation of bootstrapping result

[hsk22@cam.ac.uk]

Dear statalists,

I just run bootstrapping for my coefficients of regression and got the 
results as follows:

                             N = normal, P = percentile, BC = 
bias-corrected


On the results, what does it mean bias? When I report the confidence 
interval, Do I have to report
BC(bias-corrected) or just Normal? I really appreciate if anybody comment 
on this. Thanks in advance.
