DOI: 10.1007/s00500-019-04348-x
Abstract: In this note we prove that divisible residuated semilattices have some specific algebraic properties. We show that: (1) for normal and divisible residuated semilattices representability is equivalent to the existence of a join term, (2)… read more here.

DOI: 10.1017/s0004972718000746
Abstract: We give a simple argument which shows that Gabor systems consisting of odd functions of $d$ variables and symplectic lattices of density $2^{d}$ cannot constitute a Gabor frame. In the one-dimensional, separable case, this follows… read more here.

DOI: 10.1177/0013164417717314
Abstract: Mplus is a powerful latent variable modeling software program that has become an increasingly popular choice for fitting complex item response theory models. In this short note, we demonstrate that the two-parameter logistic testlet model… read more here.

DOI: 10.1515/ijnsns-2018-0375
Abstract: Abstract The Sylvester–Kac matrix, also known as Clement matrix, has many extensions and applications. The evaluation of determinant and spectra of many of its generalizations sometimes are hard to compute. Recently, E. Kılıç and T.… read more here.

A Short Note on Aberrant Responses Bias in Item Response Theory
Sign Up to like & getrecommendations! Published in 2019 at "Frontiers in Psychology"
DOI: 10.3389/fpsyg.2019.00043
Abstract: Item response models often cannot calculate true individual response probabilities because of the existence of response disturbances (such as guessing and cheating). Many studies on aberrant responses under item response theory (IRT) framework had been… read more here.
