Refuting "Debunking the GAMLSS Myth: Simplicity Reigns in Pulmonary Function Diagnostics"
Robert A. Rigby, Mikis D. Stasinopoulos, Achim Zeileis +7
We read with interest the above article by Zavorsky (2025, Respiratory Medicine, doi:10.1016/j.rmed.2024.107836) concerning reference equations for pulmonary function testing. The…
Simultaneous Estimation and Model Choice for Big Discrete Time-to-Event Data with Additive Predictors
Benjamin Müller, Nikolaus Umlauf, Johannes Seiler +2
Discrete-time hazard models are widely used when event times are measured in intervals or are not precisely observed. While these models can be estimated using standard generalized…
Generalized Multivariate Functional Additive Mixed Models for Location, Scale, and Shape
Alexander Volkmann, Nikolaus Umlauf, Sonja Greven
We propose a flexible regression framework to model the conditional distribution of multilevel generalized multivariate functional data of potentially mixed type, e.g. binary and c…
Stagewise Boosting Distributional Regression
Mattias Wetscher, Johannes Seiler, Reto Stauffer +1
Forward stagewise regression is a simple algorithm that can be used to estimate regularized models. The updating rule adds a small constant to a regression coefficient in each iter…
