Eighty Univariate Distributions and Their Relationships Displayed in a Matrix Format

This work improves upon previously published results by depicting 80 probability distributions in one user-friendly ten-by-eight matrix format. The figure is logically organized and thereby allows users to easily locate a particular distribution. A simplified five-by-five matrix, showing only 25 families, is designed for more elementary needs. These distributions and associated relationships provide rapid access to information that must otherwise be found through a time-consuming search of numerous sources.
