Analysis of neonatal clinical trials with twin births
BMC Medical Research Methodology, 2009 Background In neonatal trials of pre-term or low-birth-weight infants, twins may represent 10–20% of the study sample. Mixed-effects models and generalized estimating equations are common approaches for handling correlated continuous or binary data ...

Generalized single-index models: The EFM approach [PDF]
Generalized single-index models are natural extensions of linear models and circumvent the so-called curse of dimensionality. They are becoming increasingly popular in many scientific fields including biostatistics, medicine, economics and finan- cial ...

Schauder Estimates for Equations Associated with Lévy Generators [PDF]
Integral Equations and Operator Theory, 2019 We study the regularity of solutions to the integro-differential equation $Af- f=g$ associated with the infinitesimal generator $A$ of a L vy process. We show that gradient estimates for the transition density can be used to derive Schauder estimates for $f$.

Effects of Biological Sex and Age on Cerebrospinal Fluid Markers—A Retrospective Observational Study
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cerebrospinal fluid (CSF) analysis is a key diagnostic tool for neurological diseases. To date, only a few studies have investigated in larger cohorts the effect of age and biological sex on diagnostic markers extracted from CSF. Methods For this retrospective observational study, 4163 CSF findings (2012–2020) were evaluated.

The analysis of correlated non-Gaussian outcomes from clusters of size two: non-multilevel-based alternatives? [PDF]
, 2012 In this presentation we discuss the analysis of clustered binary or count data, when the cluster size is two. For Gaussian outcomes, linear mixed models taking into account the correlation within clusters, are frequently used and well understood. Here we
