Simulation input models: Relationships among eighty univariate distributions displayed in a matrix format

This paper presents a user-friendly display, in a ten-by-eight matrix format, of a collection of 80 univariate distributions and their interrelationships. A simplified five-by-five matrix, showing only 25 families, is designed for student use. These relationships provide rapid access to information that must otherwise be found through a time-consuming search of numerous sources.
