Rasch-based high-dimensionality data reduction and class prediction with applications to microarray gene expression data [PDF]
Expert Systems with Applications, 2010;37(7):5178-5185, 2010 Class prediction is an important application of microarray gene expression data analysis. The high-dimensionality of microarray data, where number of genes (variables) is very large compared to the number of samples (obser- vations), makes the application of many prediction techniques (e.g., logistic regression, discriminant analysis) difficult.

A Rasch analysis of the Burnout Assessment Tool (BAT)
PLOS ONE, 2020 Burnout as a concept indicative of a work-related state of mental exhaustion is recognized around the globe. Numerous studies showed that burnout has negative consequences for both individuals and organizations but also for society at large, especially in welfare states where sickness absence and work incapacitation are covered by social funds.

Is the d2 Test of Attention Rasch Scalable? Analysis With the Rasch Poisson Counts Model [PDF]
Perceptual and Motor Skills, 2018 The d2 test is a cancellation test to measure attention, visual scanning, and processing speed. It is the most frequently used test of attention in Europe. Although it has been validated using factor analytic techniques and correlational analyses, its fit to item response theory models has not been examined.

Structural properties of Pb3Mn7O15 determined from high-resolution synchrotron powder diffraction [PDF]
J. Solid State Chem. 182, 1188 (2009), 2008 We report on the crystallographic structure of the layered compound Pb3Mn7O15. Previous analysis based on laboratory X-ray data at room temperature gave contradictory results in terms of the description of the unit cell. Motivated by recent magnetic bulk measurements of this system, we re-investigated the chemical structure with high-resolution ...

The Role of Syllables in Anagram Solution: A Rasch Analysis [PDF]
The Journal of General Psychology, 2011 Anagrams are frequently used by experimental psychologists interested in how the mental lexicon is organized. Until very recently, research has overlooked the importance of syllable structure in solving anagrams and assumed that solution difficulty was mainly due to frequency factors (e.g., bigram statistics).
