Distribution graph

#### Description

This is a calculator for the log-logistic distribution with scale parameter $$a$$ and shape parameter $$b$$. 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 paramters $$a$$ and $$b$$ and the variables $$x$$ and $$p$$ can be varied with input controls. Either CDF view or PDF view can be selcted.
