Hello R users!
I would like to compare and describe variance within and between sites with
differing numbers of observations. My dataset has 90 clusters with varying
numbers of observations in each cluster Can someone suggest the best way to
compare within and between site variances in R? Or point me to a relevant
post?
Here is an example to play with if needed:
clust<-rep(1:10, sample(c(7,10), 10, replace=T))
variable<-abs(rnorm(length(clust)))
data<-data.frame(cbind(clust, variable))
Thank you for your help!
