What is the Diffusion Coefficient used in this package?

[tejas-savalia]

In HDDM, the noise coefficient (scaling parameter) is documented to be set to 1 (here).
I couldn't find an equivalent documentation for HSSM. Would be useful information to have for interpretability!

Hi @tejas-savalia,

we should add this explicitly in the documentation, but indeed, the noise coefficient is set coherently to 1 for all models based on diffusion.

Thank you!
