Hello, What is the proper way to specify a theano shared variable that represents a nominal predictor in a given model? I wish to be able to perform the model inference using the shared variable from the train set and then perform the sampling from the ppc in the test set. I anticipate that the s…

Nope, what I meant is: specifying a_1 as a_1 = pm.Normal('a_1', mu=0.0, tau=1 / a_1_sigma ** 2, shape=2) However, if in your testing set there is a 3rd category, then it will break the code as indexing a_1[2] will return an error. In this case, you need to instead specify a_1 as a_1 = pm.Normal('…

But, in the face of no data for test=[2], shouldn’t it just draw from N(0, 1 / a_1_sigma ** 2)?
