dear all,I need help. I want to make bootstrapping regression with fixed -X (i.e. resample from the error). I found the error (e) and made the resample using the following functionee<-matrix(sample(e,n*nboot,replac=T,nrow=nboot)in this case I had a matrix with the nboot bootstrap error.I need now to find formula yb[i]=fit+ee[i], where fit is known.How to make this?See More
