Hi, i am trying to find an appopriate R function which will estimate the bias associated with the apparent error rate of my logistic discriminant model (groups = 2, covariates = 3). I have read that bootstrapping can be used for this. Does anyone have any ideas on how I can go about doing this? I have quite a small sample size for one of my groups and I realize this may cause some problems, but
