Dear all,
I am running the "Raschtest" command on four dichotomous variables
to analyze fit for an index variable. I used the following
command: "raschtest Q5_111 Q5_114 Q5_113 Q5_112, id(hhid)".
However, I received the following error message: "(Files with residence episodes and individual characteristics) At least one group of scores concerns none individuals. Tests will be not computed. Use the group or the autogroup options."
I tried both options (group or autogroup) but I still receive the same error message. Is there any way to fix this and compute the tests I
need? Your help would be very much appreciated.
Thanks in advance,
Ousmane
Nairobi, Kenya
