Detection of Differential Item Functioning with Non-Linear Regression: Non-IRT Approach Accounting for Guessing
Drabinová, Adéla; Martinková, Patrícia
2016 - anglický In this article, we present a new method for estimation of Item Response Function and for detection of uniform and non-uniform Differential Item Functioning (DIF) in dichotomous items based on Non-Linear Regression (NLR). Proposed method extends Logistic Regression (LR) procedure by including pseudoguessing parameter. NLR technique is compared to LR procedure and Lord’s and Raju’s statistics for three-parameter Item Response Theory (IRT) models in simulation study based on Graduate Management Admission Test. NLR shows superiority in power at low rejection rate over IRT methods and outperforms LR procedure in power for case of uniform DIF detection. Our research suggests that the newly proposed non-IRT procedure is an attractive and user friendly approach to DIF detection.

Report on the Last Work by Dr. Erich Nuding
Rohn, Jiří
2016 - anglický This is a facsimile copy of a 1994 report on the unpublished last paper by Dr. Erich Nuding. It is being made public here in the hope that even after twenty-two years it may be of interest for researchers working in the area of interval computations because of the intriguing concept of the "fourth modality" which has not been rediscovered during a quarter of century which has elapsed since its original formulation.

The Distribution Mapping Functions
Jiřina, Marcel
2015 - anglický The target of this study is to make clear the difference of the distribution mapping function introduced in 2003 and the classical notion of point processes theory, the counting function N, Ripley’s K-function, and other two distance functions, F and G-functions. We summarize here necessary starting points from the point process theory using the famous work by Baddeley, a two-volume book of Daley and Vere-Jones and short paper by Dixon. When dealing with the distribution mapping function we use up-to-date formulations used in various papers since 2003.
