Dear all,
I am working with a set of categorical variables labelled: Group1, Group2, Group3, and Group4. I created a new categorical variables where I replaced the observation Goup1 to Group4 by 1 to 4. Then I performed Ordinary Kriging on the new variable [1-4]. But the outcome of the kriging ranges only from 2.0 to 3.5. Basically Goup1 is lost.
Please tell me what I am doing wrong. Also please let me know how to do interpolation on categorical variables in general.
Thanks,
