I am doing a generalized linear regression with Negative Binomial likelihood. This problem is different from a typical linear model where the x and y values are separate from each other. I am looking at timeseries data, where for each values in the series, I regress on the previous W values. I would…

My original solution wasn’t working because I had defined my distribution as a subclass of pm.Discrete, which defines univariate distributions. After reading some more of the documentation, I realized that the best way to do this was to define a custom likelihood function that took as arguments all …
