I’m trying to use reduce_sum with a multilevel VAR, and I’m having trouble trying to figure out how to wrangle my data structure to work with reduce_sum (or if it’s even possible). My units are regions, nested within countries. The model partially pools at the country level (country-level random in…

the first argument of the partial-sum function must be an array of whatever is being sliced. To make progress in this case i suggest you to Do NOT use reduce_sum to start! Define two functions: a function for summing a region - call it region_lpdf, for example define a “partial_sum” function whic…

Great, thank you - it finally makes sense to me! I’ll have to rethink the data structure a bit to make that work, but very doable. Thanks so much for the help!
