Hi. Is there a way to group various subsets of random variables into a single vector to use in vector operations? For example, say my model looks something like: a = pm.Normal(…, shape=4) b = pm.Normal(…, shape=7) and I would like to compute something like the dot product of [ a[2], b[1], b[2], b…

You should be able to wrap it in pm.Deterministic:

vec = pm.Deterministic('vec', pm.math.concatenate( (a[2:3], b[1:5]), axis=0))
