Hello folks
There seems to be a bug somewhere in the link function or model definition in the Mundlack Machine script.
In line 151 from https://github.com/rmcelreath/stat_rethinking_2024/blob/main/scripts/12_bonus_mundlak.r#L151 you are creating predictions from the posterior samples on top of the data.
But I keep getting the following error
> pf0 <- link(mf,data=list(g=1:N_groups,X=rep(0,N_groups)))
Error in Z[TRUE, g[i]] : incorrect number of dimensions
And it seems due to the usage of g as an index variable, but I couldn't figure it out.
