Measuring covariate balance in weighted propensity score analyses by the weighted z-difference

Authors: Tim Filla, Holger Schwender, Oliver Kuß

arXiv

Propensity score (PS) methods have been increasingly used in recent years when assessing treatment effects in nonrandomized studies. In terms of statistical methods, a number of new PS weighting metho...

On approximate robust confidence distributions

Authors: Elena Bortolato, Laura Ventura

arXiv

A confidence distribution is a complete tool for making frequentist inference for a parameter of interest $ψ$ based on an assumed parametric model. Indeed, it allows to reach point estimates, to asses...

Validating argument-based opinion dynamics with survey experiments

Authors: Sven Banisch, Hawal Shamon

arXiv

The empirical validation of models remains one of the most important challenges in opinion dynamics. In this contribution, we report on recent developments on combining data from survey experiments wi...

Non-linear, bivariate stochastic modelling of power-grid frequency applied to islands

Authors: Ulrich Oberhofer, Leonardo Rydin Gorjão, G. Cigdem Yalcin, Oliver Kamps, Veit Hagenmeyer, Benjamin Schäfer

arXiv

Mitigating climate change requires a transition away from fossil fuels towards renewable energy. As a result, power generation becomes more volatile and options for microgrids and islanded power-grid...

Deep Spectral Q-learning with Application to Mobile Health

Authors: Yuhe Gao, Chengchun Shi, Rui Song

arXiv

Dynamic treatment regimes assign personalized treatments to patients sequentially over time based on their baseline information and time-varying covariates. In mobile health applications, these covari...

Modelling cortical network dynamics

Authors: Gerald K. Cooray, Richard E. Rosch, Karl J. Friston

arXiv

We consider the theoretical constraints on interactions between coupled cortical columns. Each column comprises a set of neural populations, where each population is modelled as a neural mass. The exi...
