1. Try the following in 63.3 y <- rnorm(20) y1 <- y[2:20] y2 <- y[1:19] summary(glm(y1~offset(y2))) summary(glm(y1-y2~1)) Both are the same model, but the first gives the wrong s.e. I don't believe this was a problem in 63.2
My apologies: I have mis-edited the patch I applied, working too close
to the deadline for 0.64. I have in glm.fit
residuals[good] <- z - (eta + offset)[good] # z does not have
Change + to - .
Oh well, 0.64.1 may get this right.
