XLispStat is a statistical scientific package based on the XLISP language.

Many free statistical software like [http://www.stat.umn.edu/arc/ ARC] (nonlinear curve fitting problems) and ViSta are based on this package.{{citation needed|date=January 2016}}

It includes a variety of statistical functions and methods, including routines for nonlinear curve fit.{{citation needed|date=January 2016}} Many add-on packages have been developed to extend XLispStat, including contingency tables{{cite conference|last1=Badsberg|first1=J.

XLispStat has seen usage in many fields, including astronomy,{{cite book|author1=G. Jogesh Babu|author2=Eric D.

XLispStat was historically influential in the field of statistical visualization.{{cite book|author1=Forrest W. Young|author2=Pedro M.

Its author, Luke Tierney, wrote a 1990 book on it.{{cite book|author=Luke Tierney|title=LISP-STAT: An Object-Oriented Environment for Statistical Computing and Dynamic Graphics|url=https://books.google.com/books?id=ie_KKAamFM4C&pg=PR3|date=25 September 2009|orig-year=1990|publisher=John Wiley & Sons|isbn=978-0-470-31756-3}}

XLispStat dates to the late 1980s/early 1990s and probably saw its greatest popularity in the early-to-mid 1990s with greatly declining usage since. In the 1990s it was in very widespread use in statistical education, but has since been mostly replaced by R. There is a paper explaining why UCLA's Department of Statistics abandoned it in 1998,{{cite journal |title=On Abandoning XLISP-STAT |journal=Journal of Statistical Software |date=February 2005 |last=de Leeuw |first=Jan |volume=13 |issue=7 |issn=1548-7660 |url=https://www.jstatsoft.org/article/view/v013i07/v13i07.pdf |access-date=2017-05-30 }} and their reasons for doing so likely hold true for many other of its former users.
