Distribution graph


This is a simple calculator for the triangle distribution on the interval \( [a, a + w] \) with vertex at \( a + p w \). 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 \(x = F^{-1}(q)\) for a given value of \(q\). The location parameter \(a\), the scale parameter \(w\), the shape parameber \(p\), and the variables \(x\) and \(q\) can be varied with the input controls. Either CDF view or PDF view can be selcted.
