XLISP-STAT is an extensible system for statistical computing and dynamic graphics which is based on a dialect of Lisp called XLISP (developed by David Betz). To facilitate statistical computations the author modified standard Lisp functions for addition, logarithms, etc., to operate on lists and arrays of numbers, and also added a number of basic statistical functions. Several basic forms of plots, including histograms, scatterplots, 3-dimensional rotatable plots and scatterplot matrices are provided. These plots support various forms of interactive highlighting operations and can be linked so points highlighted in one plot will be highlighted in all linked plots. Interactions with the plots are controlled by the mouse, menus and dialog boxes. An object-oriented programming system is used to make it possible to customize menus, dialogs, and the way plots respond to mouse actions.

An manual of over 100 pages is provided in LaTeX form. More complete documentation is published as a book, "Lisp-Stat: An object-oriented environment for statistical computing and dynamic graphics", that is available from Wiley. Some of the chapter headings from the manual include Regression, Matrices and Arrays, Nonlinear Regression, One Way ANOVA, Maximization and Maximum Likelihood Estimation, and Approximate Bayesian Computations.
