Problem with HSSM vs HDDM

[oajilore]

Hello,

I have a dataset that I have tried use HSSM with but I can never get stable estimates for the DDM parameters. I always get multiple divergences. However, when I used the dockerHDDM package, it worked great with the same data.

• Is there a reason why the modeling the same data would fail with HSSM but work for the legacy HDDM package?

• Are there any settings for HSSM that I need change to make it perform like the previous version of HDDM?

Thanks for your help!
