چکیده

response theory modeling is affected by the reliability of the items, the test length, the type of aberrant response behavior, and the percentage of aberrant persons in the group. The percentage of simulees defined a priori as aberrant responders that were detected increased when the mean item reliability, the test length, and the ratio of aberrant to nonaberrant simulees in the group increased. Also, simulees "cheating" on the most difficult items in a test were more easily detected than those "guessing" on all items. Results were less stable across replications as item reliability or test length decreased. Results suggest that relatively short tests of at least 17 items can be used for person-fit analysis if the items

Closed-Form Estimation of Nonparametric Models with Non-Classical Measurement Errors

This paper proposes closed-form estimators for nonparametric regressions using two measurements with non-classical errors. One (administrative) measurement has location/scale-normalized errors, but the other (survey) measurement has endogenous errors with arbitrary location and scale. For this setting of data combination, we derive closedform identification of nonparametric regressions, and pra...

Statistical Modeling of Expert Ratings on Medical Treatment Appropriateness

This article uses latent structure analysis to model ordered category ratings by multiple experts on the appropriateness of indications for the medical procedure carotid endarterectomy. The statistical method used is a form of located latent class analysis, which combines elements of latent class and latent trait analysis. It assumes that treatment indications fall into distinct latent classes,...

Evaluating the quality of analytic ratings with Mokken scaling

Greatly influenced by the work of Rasch (1960/1980), Mokken (1971) presented a nonparametric scaling procedure that is based on the theory of invariant measurement, but draws upon less strict requirements related to the scale of measurement. Because they are theoretically and empirically related to Rasch models, Mokken’s nonparametric models have been recognized as a useful exploratory tool for...

Correction for covariate measurement error in nonparametric regression

Many areas of applied statistics have become aware of the problem of measurement error-prone variables and their appropriate analysis. Simply ignoring the error in the analysis usually leads to biased estimates, like e.g. in the regression with error-prone covariates. While this problem has been discussed at length for parametric regression, only few methods exist to handle nonparametric regres...

Nonparametric Errors in Variables Models with Measurement Errors on both sides of the Equation∗

Measurement errors are often correlated, as in surveys where respondent’s biases or tendencies to err affect multiple reported variables. We extend Schennach (2007) to identify moments of the conditional distribution of a true Y given a true X when both are measured with error, the measurement errors in Y and X are correlated, and the true unknown model of Y given X has nonseparable model error...
