@dylanhmorris @sbidari Do we need to make any changes about what is in the deterministic module?

Potentially move DeterministicVariable to the randomvariable module? @dylanhmorris mentioned it in the issue comment.
But since DeterministicVariables are not really random variables, it might make more sense to leave them in the deterministic module?

[damonbayer]

We agreed not to move the DeterministicVariable class at this time.

@sbidari is this ready for review?

@sbidari is this ready for review?

Waiting for #356, I unintentionally created this branch with changes from #356

[damonbayer]

@sbidari #356 is merged. Please mark this as "ready for review" when it's ready for review.

[damonbayer]

Looks like the merge undid some changes from #356.

[damonbayer]

Thanks @sbidari!

My approval was premature. The randomvariable module documentation needs to be added to the website.
