Nonparametric Person-Fit Research: Some Theoretical issues an Empirical Example
Applied Measurement in Education, 1996In person-fit analysis, it is investigated whether an item score pattern is improbable given the item score patterns of the other persons in the group or given an expected score pattern on the basis of a test model. In this study, several existing group-based statistics are discussed to detect such improbable item score patterns, along with the cut ...

The idea of whether a person's response pattern is "believable" given his estimated ability is one of the central issues in measurement. This article traces the development of this idea from Thurstone to Rasch. It also presents the rationale behind the development of person analysis in the Rasch model.

Person fit in discussed from the perspective of testing whether or not an individual’s test behavior is consistent with the Rasch model. A general method is considered for deriving person fit indices and person fit tests that are powerful for testing against a prespecified type of deviation from the Rasch model.

Testing Person Fit in Cognitive Diagnosis
Applied Psychological Measurement, 2009In cognitive diagnosis, the test-taking behavior of some examinees may be idiosyncratic so that their test scores may not reflect their true cognitive abilities as much as that of more typical examinees. Statistical tests are developed to recognize the following: (a) nonmasters of the required attributes who correctly answer the item (spuriously high ...

Educational Measurement: Issues and Practice, 2013
The goal of this study was to investigate the usefulness of person‐fit analysis in validating student score inferences in a cognitive diagnostic assessment. In this study, a two‐stage procedure was used to evaluate person fit for a diagnostic test in the domain of statistical hypothesis testing.

Constructing the Exact Significance Level for a Person Fit Statistic
Psychometrika, 1992This paper uses an extension of the network algorithm originally introduced by Mehta and Patel to construct exact tail probabilities for testing the general hypothesis that item responses are distributed according to the Rasch model. By assuming that item difficulties are known, the algorithm is applicable to the statistical tests either given the ...

Adjusted Rasch person-fit statistics.
Journal of applied measurement, 2006Two frequently used parametric statistics of person-fit with the dichotomous Rasch model (RM) are adjusted and compared to each other and to their original counterparts in terms of power to detect aberrant response patterns in short tests (10, 20, and 30 items). Specifically, the cube root transformation of the mean square for the unweighted person-fit
