A Multidimensionality-Based DIF Analysis Paradigm
Applied Psychological Measurement, 1996 A multidimensionality-based differential item functioning (DIF) analysis paradigm is presented that unifies the substantive and statistical DIF analysis approaches by linking both to a theoretically sound and mathematically rigorous multidimensional ...

Proceedings RIDE '96. Sixth International Workshop on Research Issues in Data Engineering, 2002
Most computerized data is not under the purview of traditional database management systems, but, rather, it is stored in files. Data Interchange Formats (DIFs) are the basis of an important class of such files, containing massive volumes of data, and serving a large user community.

Not all DIF is shaped similarly
Psychometrika, 2021In response to the target article by Teresi et al. (2021), we explain why the article is useful and we also present a different approach. An alternative category of differential item functioning (DIF) is presented with a corresponding way of modeling DIF, based on random person and random item effects and explanatory covariates.

Broadband development and firm creation: Dif-in-dif estimates for Germany
AHFE International, 2022Although some of the outcomes of the digital transformation are reflected in the scientific literature, the connection between high-speed internet transmission rates and firm entries is still poorly studied. While some positive impact of basic broadband availability in Germany was found in our previous studies, in this paper we decided to examine the ...

Applied Psychological Measurement, 2010
Practitioners are increasingly becoming interested in Differential Item Functioning (DIF) forimproving the validity of test and scale interpretations. Among the statistical procedures availableto assess DIF in dichotomous and polytomous items, the Mantel-Haenszel chi-square (1959) andother standardization proceduresmay beparticularly attractive to ...

An Examination of Item Context Effects, DIF, and Gender DIF
Applied Measurement in Education, 2001This investigation examined whether the patterns of gender differential item functioning (DIF) present in parcels of items are influenced by changes in item position. Items were studied collectively to detect differential bundle functioning (DBF) on 2 forms of a test of mathematics for college freshmen. To investigate order effects, 2 forms of the test

DIF Algorithms for DCT and DST
ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Decimation-In-Frequency (DIF) algorithms for a family of discrete cosine and sine transforms (DCT) and (DST) are systematically developed, based on a radix-2 factorization of the transformation matrices. The results indicate these to be viable alternatives to existing algorithms for the calculation of these discrete transforms.

The DIF-Free-Then-DIF Strategy for the Assessment of Differential Item Functioning
Educational and Psychological Measurement, 2012The DIF-free-then-DIF (DFTD) strategy consists of two steps: (a) select a set of items that are the most likely to be DIF-free and (b) assess the other items for DIF (differential item functioning) using the designated items as anchors. The rank-based method together with the computer software IRTLRDIF can select a set of DIF-free polytomous items very

Functional DIF for Rapid Prototyping
2008 The 19th IEEE/IFIP International Symposium on Rapid System Prototyping, 2008Dataflow formalisms have provided designers of digital signal processing systems with optimizations and guarantees to arrive at quality prototypes quickly. As system complexity increases, designers are expressing more types of behavior in dataflow languages to retain these implementation benefits.

NodeGit : Diffing and Merging Node Graphs
ACM Transactions on Graphics, 2023The use of version control is pervasive in collaborative software projects. Version control systems are based on two primary operations: diffing two versions to compute the change between them and merging two versions edited concurrently. Recent works provide solutions to diff and merge graphics assets such as images, meshes and scenes.
