'''Join count statistics''' are a method of [[spatial analysis]] used to assess the degree of association, in particular the [[autocorrelation]], of [[Categorical variable|categorical variables]] distributed over a spatial map. They were originally introduced by Australian statistician [[P. A. P. Moran]].Moran PA. The interpretation of statistical maps. Journal of the Royal Statistical Society. Series B (Methodological). 1948 Jan 1;10(2):243-51. Join count statistics have found widespread use in [[econometrics]],Anselin L. Spatial econometrics. Handbook of spatial analysis in the social sciences. 2022 Nov 15:101-22. [[remote sensing]]Congalton RG, Green K. Assessing the accuracy of remotely sensed data: principles and practices. CRC press; 2019 Aug 8. and [[ecology]].Dale MR, Fortin MJ. Spatial analysis: a guide for ecologists. Cambridge University Press; 2014 Sep 11.
