Dear R-help list,
I have grouped data, looking like this: cases <- c(23,12,56,81) total <- c(123,234,248,390) x1 <- c(0,0,1,1) x2 <- c(0,1,0,1) Data <- as.data.frame(cbind(cases,total,x1,x2)) Data I would like to run a logistic regression with group weights on these, where cases and (total-cases) are equal to the group weights (w). My final data would look like: w <- c(100,23,222,12,192,56,309,81) y <- c(0,1,0,1,0,1,0,1) x1 <- c(0,0,0,0,1,1,1,1) x2 <- c(0,0,1,1,0,0,1,1) Data.long <- as.data.frame(cbind(w,y,x1,x2)) Data.long Any suggestions?
