@yanboliang Could you help me understand the issue caused by using string?
If I use object, then I have to create a Tweedie object that is not used
anywhere else. And also I have to write two methods in `Family`: one returns
the global Tweedie object (where the variancePower is preset) and one returns
the a TweedieFamily object created using the user-specified variancePower. I
hope we are fine using string since there are only a few values.
