PDFCalc

PDFCalc is a stand-alone application that allows users to create, edit, and visualize probability density functions, examine their characteristics (their means, quartiles, and other properties), and easily generate random variates from these functions for potential use in other scripts or applications. All of the probability density functions supported by NAADSM are included in PDFCalc. PDFCalc can also be used to produce empirical histogram probability density functions from data.
