Hello,

I was wondering if anyone knew whether the principal components function in Spatial Analyst was appropriate for use on categorical variables. Since my data are in rasters they will have to be assigned integers which may result in the variables being considered continuous. Does anyone know of a way to do PCA on categorical variables in rasters?

Thanks. Any advice is appreciated!
