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?
All the best,
Oystein Myrland
