the scale on which to evaluate each subject. stype = "ObsScore" uses the subject's total score. stype = "Theta" uses the subject's rank on the thetadist scale. stype = "ThetaML" uses the maximum likelihood estimate for the subject on the thetadist scale. codestype = "ScoreML" uses the maximum likelihood estimate for the subject on the overall test score scale.
