Baseline-adjusted proportional odds models for the quantification of treatment effects in trials with ordinal sum score outcomes [PDF]
Background Sum scores of ordinal outcomes are common in randomized clinical trials. The approaches routinely employed for assessing treatment effects, such as t-tests or Wilcoxon tests, are not particularly powerful in detecting changes in relevant ...

Latent trait or sum score: addressing measurement challenges in the prediction of self-rated symptom outcomes in psychological treatment [PDF]
ObjectiveReliable and accurate measurement is fundamental to scientific progress; however, the dominant measurement practices in psychology, clinical psychology, and prediction research often lack rigor. Improving measures using Rasch Measurement Theory (

New results on perturbation-based copulas
A prominent example of a perturbation of the bivariate product copula (which characterizes stochastic independence) is the parametric family of Eyraud-Farlie-Gumbel-Morgenstern copulas which allows small dependencies to be modeled.

Monotone and cone preserving mappings on posets [PDF]
We define several sorts of mappings on a poset like monotone, strictly monotone, upper cone preserving and variants of these. Our aim is to study in which posets some of these mappings coincide.

$\aleph_1$ and the modal $\mu$-calculus [PDF]
For a regular cardinal $\kappa$, a formula of the modal $\mu$-calculus is $\kappa$-continuous in a variable x if, on every model, its interpretation as a unary function of x is monotone and preserves unions of $\kappa$-directed sets.
