Distribution graph


This is a simple calculator for the negative binomial distribution with stopping parameter \(k\) and success probability \(p\). The calculator gives the value of the cumulative distribution function \(q = F(x)\) for a given value of \(x\), or the value of the quantile function \(x = F^{-1}(a)\) for a given value of \(a\). The parameters \(k\) and \(p\) and the variables \(x\) and \(q\) can be varied with the input controls. Either CDF view or PDF view can be selcted.
