I am trying to run the "Raschtest" command on nine dichotomous variables
to analyze fit for an index variable. First, when I use the following
command - "raschtest CRIME1-CRIME9, autogroup" - I receive the following
error - "At least one group of scores concerns none individuals. Tests
will be not computed. Use the group or the autogroup options." However, as
you can see, I did use the autogroup command. And I have also tried the
group subcommand. Is there any way to fix this and compute the tests I
need? Second, do the "genscore" or "genlt" subcommands generate each
person's ability parameter? If not, is there a subcommand to accomplish
this. Any help would be appreciated.
