Special Distribution Calculator

Quantile graph
Distribution graph


This 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 \(x = F^{-1}(q)\) for a given value of \(q\). The value \( x \) and the cumulative probability \( q \) are illustrated with the graph of the probability density function and the graph of the distribution function. Each of the following special distribution can be selected with the list box:

The parameters of the distribution, and the variables \(x\) and \(q\) can be varied with the input controls.
