Where can they be seen? One should know them in order to be able to select the correct midpoint/spread parameters. Even in the Gaussian function case, it is not stated if the spread equals standard deviation of the gaussian curve!!!</SPAN><BR /><SPAN>- Johanna</SPAN></BODY></HTML> Mon, 19 May 2014 10:06:52 GMT JohannaTorppa 2014-05-19T10:06:52Z fuzzy membership functions https://community.esri.com/t5/arcgis-spatial-analyst-questions/fuzzy-membership-functions/m-p/54814#M757 <HTML><HEAD></HEAD><BODY><SPAN>I did not find equations for fuzzy membership functions in the ArcGIS tutorial/web pages.
