Hi, In the Bayesian Cognitive Modeling, chapter 12.2, I want to use this model which considered the contaminant data into my own model. But the problem is that it’s so hard to converge.
You written a sentence in the file which is ‘NOTICE: In the model following I set the prior of σσ to σα,σβ,σϕ∼Uniform(0,3)σα,σβ,σϕ∼Uniform(0,3) . Otherwise the model does not converge to the desired parameters.’.
I tried the ways only use NUTS or ADVI to initialize my model just like chapter 12.2. But it doesn’t work.
So, how can I debug my own model with this contaminant data structure?
