DistMixer allows the creation of mixture densities from any user-defined set of probability density functions. Users can specify an arbitrary number of probability density functions, and can specify the relative frequency with which samples will be drawn from each of the distributions. DistMixer produces a single probability density function that closely approximates the resulting mixture density. Output functions generated by DistMixer can be used in any application that will accept an empirical histogram probability density function, for example, NAADSM, WH, or PDFCalc.
