WebI'm trying to implement an ordered probit model in pymc, and I'm stuck. The model is similar to Welinder's "multidimensional wisdom of crowds", with coders (indexed by i) and documents (indexed by j). Coders assign codes to documents, but the coding process is noisy. We wish to estimate two things.
