Struggled with -> RuntimeError: Initialization failed about mmm_stan HOT 2 CLOSED

Hello!

One of my readers had "RuntimeError: Initialization failed" whiling running my code with her data, and here's her solution:
"I realized the issue is with Y variable. I made sure there were no missing data and all positive in Y. But there are good amount of Y which are 0. upon imputing them with mean, I could build the model."

I think errors at the sampling stage are highly likely to be related to the input data. You may want to check your data quality or if the data meet the constraints specified in the model code "data" section (e.g., specified x<lower=0>, but the actual data 'x' has negative values).

Hi Sibyl,

Thanks for you quick response, I could fix it, I hope I will not have to disturb you any more in the future.

Once again, thank you so much.
