I would like to run the PCA on the correlation, not the covariance, matrix derived from the dataset. Arc definitely calculates a correlation matrix because it is included in the output, however it seems to calculate the resulting cell values from the covariance matrix. Is there any way to produce a correlation matrix set of PCs?</SPAN><BR /><BR /><SPAN>Thanks very much,</SPAN><BR /><BR /><SPAN>Mo</SPAN></BODY></HTML> Fri, 04 Oct 2013 18:31:58 GMT MaureenCorrell 2013-10-04T18:31:58Z Calculating PC values on a correlation matrix https://community.esri.com/t5/spatial-statistics-questions/calculating-pc-values-on-a-correlation-matrix/m-p/561463#M1792 <HTML><HEAD></HEAD><BODY><SPAN>Hello all-</SPAN><BR /><BR /><SPAN>I am working on running a PCA on a composite band raster within Arc.
