Partial credit model and pivot anchoring.
Journal of applied measurement, 2002This article contains information on the Rasch measurement partial credit model: what it is, how it differs from other Rasch models, when to use it, and how to use it. The calibration of instruments with increasingly complex items is described, starting with dichotomous items and moving on to polychotomous items using a single rating scale, and mixed ...

Is the partial credit model a Rasch model?
Journal of applied measurement, 2012A balance scale metaphor is offered as a tool for explaining the principles of measurement and for visualizing the internal structure of dichotomous and polytomous Rasch models. The balance scale metaphor is used to guide the derivation of a general polytomous Rasch model and to illustrate the additional assumptions subsequently required to derive the ...

Modeling Sovereign Credit Risk under Partial-information
2014In this study we model the dynamics of sovereign credit spreads. Specifically, we interpret credit spreads as the noisy observations of some state process which represents the financial strength of the sovereigns under consideration. This naturally gives rise to a partial-information setting in which, the default history of the sovereigns constitutes ...

The impact of model misfit on partial credit model parameter estimates.
Journal of applied measurement, 2004The partial credit model (PCM) is commonly employed to parameterize items and individuals using responses to a set of polytomous items. Because the PCM does not include a discrimination parameter, it may encounter substantial lack of fit to the data in certain situations.
