Hi Chad,
maybe I can help. I believe it works the same way as with other priors. For instance:
import numpy as np
model_config["gamma_control"] = {
"dist": "TruncatedNormal",
"kwargs": {
"mu": 0.5, # same mu etc. for all controls
"lower": 0,
"upper": np.inf,
"sigma": [1,2] # [discounts, holidays]
}
}
Hope I dont have a typo, I cannot test it right now.
Best Regards
Jonas
