A tool to determine the degrees of freedom in tree-structured varying coefficient models
Nikolai Spuck, Moritz Berger
The tree-structured varying coefficient (TSVC) model is a flexible approach for generalized regression, where the linear effects of the covariates are allowed to vary with the valu…
A Simulation Study to Compare Inferential Properties when Modelling Ordinal Outcomes: The Case for the (Plain but Robust) Proportional Odds Model
Stefan Inerle, Markus Pauly, Moritz Berger
Ordinal measurements are common outcomes in studies within psychology, as well as in the social and behavioral sciences. Choosing an appropriate regression model for analysing such…
Modeling the Ratio of Correlated Biomarkers Using Copula Regression
Moritz Berger, Nadja Klein, Michael Wagner +1
Modeling the ratio of two dependent components as a function of covariates is a frequently pursued objective in observational research. Despite the high relevance of this topic in…
Non Proportional Odds Models are Widely Dispensable -- Sparser Modeling based on Parametric and Additive Location-Shift Approaches
Gerhard Tutz, Moritz Berger
The potential of location-shift models to find adequate models between the proportional odds model and the non-proportional odds model is investigated. It is demonstrated that thes…
Transition Models for Count Data: a Flexible Alternative to Fixed Distribution Models
Moritz Berger, Gerhard Tutz
A flexible semiparametric class of models is introduced that offers an alternative to classical regression models for count data as the Poisson and negative binomial model, as well…
Assessing the Calibration of Subdistribution Hazard Models in Discrete Time
Moritz Berger, Matthias Schmid
The generalization performance of a risk prediction model can be evaluated by its calibration, which measures the agreement between predicted and observed outcomes on external vali…
