This looks good to me. The one omission is alpha=0.0 in the Wald distribution. I suspect that it's also of type Optional[DIST_PARAMETER_TYPES] but default to =1.0 rather than =None.

Thank you for the feedback. I will make the necessary changes.

@cluhmann I have added more type hints to distribution parameters and typed the Wald distribution as you suggested.

[cluhmann]

Looks great to me. I am going to approve this to get the workflows working and then we can see where things are at. Someone should sanity check the changes just to make sure I haven't missed anything before merging.

[cluhmann]

I lied (I'm not qualified). Can someone review so we can see how all the CI shakes out?

If I am reading the log correctly, this seems to be some plotting/Tcl error on windows? Does that have anything to do with this PR?

[ricardoV94]

If it's the GP plot test it crops up now and then. No idea why

[cluhmann]

Ah. That seems to be it.
