I ran the sep tests for location - a discrete variable for DEA and received the error bellow:
test.sep.disc(x, y, zlocation
, ESTIMATOR = 1, ORIENTATION = 2, METRIC = 1
, NSPLIT = 10, NREP = 1000, errchk = TRUE)
Error in test.sep.disc(x, y, zlocation, ESTIMATOR = 1, ORIENTATION = 2, :
In call to test.sep.disc Z contains more than 2 categories, but the maximum value in Z is different from the number of unique values.
Even though my variable had 5 values from 1 to 5, I still received this kind of message.
Could anyone help me out?
