Hi,
Thanks for the interest and in helping out. I appreciate it.
Covariance is in Math\Statistics\RandomVariable. See if that does what you want.
For static vs object methods, a lot of math functions are input and output, so it makes sense to be static. However, whenever I get to linear algebra, I was planning on having classes for Vector and Matrix etc. and they would have object methods to do various matrix operations. Basically, any time where you would want to do multiple operations on the same data, I think it makes sense to make an object.
I see what you are thinking with Regressions. I think that would be a good design change, especially considering there are functions to evaluate for y based on the regression parameters.

I've refactored Regressions into individual classes that are instantiated, which extend a base Regression class.
