    Recursive relationship: binomial, poisson, and negative binomial distribution

    ON a section learning about different types of discrete distributions, the last page was this:

    What does the recursive relationships mean and why are they so important to know?

    Re: Recursive relationship: binomial, poisson, and negative binomial distribution

    A recursive relationship means a term of a given sequence can be computed in terms of one or more of the previous members of the sequence.

    Something like

    $s_k = f(s_{k-1},~s_{k-2},\dots,~s_1)$

    They are useful to know for actually calculating values and sometimes the recursion itself can reveal underlying principles of the sequence.
