Hello, I’m new to PyMC and Bayesian statistics, so forgive me if this is a dumb question. I’m running a script that does MCMC sampling using the NUTS sampler. The dataset is split into 2 groups (treatment and baseline), and each row represents the batch yield (%) of a batch. The rows are also label…

I think you might be running into compilation time issues. You can avoid all recompilation if you use nutpie to sample: import pymc as pm import numpy as np import pytensor.tensor as pt dataBaseline = np.random.randn(8000) dataTreatment = np.random.randn(8000) with pm.Model() as model: dataB…

Strange, looks like a very simple model. What’s the size of your dataset?
