SAS forest algorithms are designed to handle millions of observations. The proximity matrices would be too large.&nbsp; There hasn't been sufficient user interest to motivate&nbsp;figuring out some solution.</P> <P>-Padraic</P> Fri, 09 Feb 2018 20:47:50 GMT https://communities.sas.com/t5/SAS-Data-Science/Getting-a-proximity-matrix-from-a-random-forest/m-p/435849#M6714 PadraicGNeville 2018-02-09T20:47:50Z
