Good link to suggest for non-centering parametrization?

[mike-lawrence]

And note this trick to easily toggle between the two parameterizations:

FYI: how to easily toggle between centered/non-centered

Because I haven’t seen it anywhere else, I thought I’d share what I came up with to encode a model with runtime selection of centered versus non-centered parameterizations for hierarchical parameters: data { // K: number of identifiable-units-of-observation (IUOO) int K ; // N: number of observations total (must be at least one per IUOO) int<lower=K> N; // which_K: index associating each observation with its IUOO int<lower=1,upper=K> which_K[N] ; // Y: vector of observations vec…
