Hi,   I am fairly new to SAS and could use some help. I have been working on customer segmentation on a 30 000 entries data set with mixed variables (continuos, binary and categorical).   I initially was thinking of turning some of the categorical variables with few levels into binary variables and then use PROC FASTCLUS on it. However it seems like FASTCLUS only performs k-means, which is not appropriate for binary variables. I then used PROC DISTANCE to create a gower's distance matrix directly for the mixed variables data set to feed into PROC CLUSTER. But now I am getting an error  and warning:   WARNING: Unable to allocate sufficient memory. Amount requested was 0, amount available was 1691620352... ERROR: Invalid position -2147479016 for utility file WORK.'SASTMP-000000029'n.UTILITY   Am I doing something wrong or is my data set to large to be processed with PROC CLUSTER. Are there any alternative ways to cluster mixed variables ds?   Thanks 🙂 ... View more
