    This is a follow up question to: ruby variable scoping across classes. The solution makes sense to me conceptually, but I can't get it to work. Thought maybe with more code...  more

    Hello!
    I want to fit a dataset with a sum of two distribution: Gaussin + Poisson.
    The dataset can have up to 3000 numbers, this should be enough for reasonable fitting. Is there...  more
