Distribution graph


This is a simple calculator for the Irwin-Hall distribution with \(n\) terms. The calculator gives the value of the cumulative distribution function \(p = F(x)\) for a given value of \(x\), or the value of the quantile function \(x = F^{-1}(p)\) for a given value of \(p\). The parameter \(n\) and the variables \(x\) and \(p\) can be varied with the input control. Either CDF view or PDF view can be selcted.
