I’m doing a linear regression. Say I am modeling the equation y = a*x. When I plot the output of sample_posterior_predictive (y_prediction) and the calculated contribution ax, these lines do not match. I would expect them to match. Is there an error term in the model object that I need to account f…

Sum of contributions do not match model prediction
