Hi, I would like to know why I keep getting very weird initial evaluation results even though I set the initval as 1 for all my prior distributions. with pm.Model() as model: a1 = pm.HalfNormal('a1', sigma=10, initval=1) a2 = pm.HalfNormal('a2', sigma=10, initval=1) a3 = pm.Half…

Specifically, you can use the init argument to pm.sample() to select one of several difference initialization strategies (list is here ).

This makes a lot of sense. Thank you so much for sharing this valuable experience!
