I would like to fit a model wherein replicates belong to different groups (a multiple membership model), but importantly the replicates can differ in the number of groups to which they belong. What is the appropriate syntax to account for multiple membership when replicates belong to different numbe…

When I run dat <- data.frame( y = rnorm(100), x1 = rnorm(100), x2 = rnorm(100), g1 = sample(1:10, 100, TRUE), g2 = sample(1:10, 100, TRUE), w1 = rep(1, 100), w2 = c(1, rep(0, 99)) ) make_standata(y ~ x1 + (1|mm(g1, g2, weights = cbind(w1, w2))), data = dat) I see that the weights are correc…
