Hello,

is it possible to calculate a model in SAS? if it is possible. Could you please tell me how to do it?

Yes, you can calculate that statistic. Please provide some sample data in the form of a DATA step. Be sure to explain which columns correspond to the various counts. I assume you have M = max(M_i) total columns, but I don't understand how the counts for the n-digit classes are arranged/named in the data.
