Hello , Can anyone please help me figure out how to do a weighted betabinomial analysis? I mean i have 700 clusters each of size 2 and the response (y[i1]+y[i2]) in each cluster case is either 0,1...

I have a problem, would really appreciate if anyone could help me. I am trying to use bootstrap to resample a dataframe n then use that sample of dataframe to calcuate parameter estimates using betabinomial model. I am kind of...

i m not sure what u really want to do but if ur looking for some subsample of dataset then u might wanna try this (say in case u want to resample ur dataset by column "id" in ur dataset...

try something like this before wrapping up your function else i guess u'll have to stick to Prof Brian Ripley suggestion his suggestions are usually best bet . f <- function(x) { n <- length(x) r <- sum((b^(0:(n-1...
