Examples of Model-Data Fit Studies
1985In the previous chapter, a set of steps and techniques were introduced for conducting goodness-of-fit investigations. The purpose of this chapter is to highlight the applications of several of those techniques to the analysis of real data. Specifically, the results of fitting the one- and three-parameter logistic models to four mathematics tests in the

Impedance spectroscopy: Models, data fitting, and analysis
Solid State Ionics, 2005Abstract First, several impedance spectroscopy models found useful for data fitting and interpretation of dielectric- and conductive-system frequency data are briefly summarized and compared. The first of these are the Kohlrausch KD model for dielectric-system response, representing the frequency response associated with stretched-exponential ...

Applied Psychological Measurement, 2011
This study investigated the relative model—data fit of an ideal point item response theory (IRT) model (the generalized graded unfolding model [GGUM]) and dominance IRT models (e.g., the two-parameter logistic model [2PLM] and Samejima’s graded response model [GRM]) to simulated dichotomous and polytomous data generated from each of these models.

Musicae Scientiae, 2015
The purpose of this study was to investigate model-data fit and differential rater functioning in the context of large group music performance assessment using the Many-Facet Rasch Partial Credit Measurement Model. In particular, we sought to identify whether or not expert raters’ ( N = 24) severity was invariant across four school levels (middle ...

Energy Conversion and Management, 2013
A statistical distribution for describing wind direction provides information about the wind regime at a particular location. In addition, this information complements knowledge of wind speed, which allows researchers to draw some conclusions about the energy potential of wind and aids the development of efficient wind energy generation.
