Accounting for Time Dependency in Meta-Analyses of Concordance Probability Estimates
Matthias Schmid, Tim Friede, Nadja Klein +1
Recent years have seen the development of many novel scoring tools for disease prognosis and prediction. To become accepted for use in clinical applications, these tools have to be…
MetaStan: An R package for Bayesian (model-based) meta-analysis using Stan
Burak Kürsad Günhan, Christian Röver, Tim Friede
Meta-analysis methods are used to combine evidence from multiple studies. Meta-regression as well as model-based meta-analysis are extensions of standard pairwise meta-analysis in…
Adjusting for publication bias in meta-analysis via inverse probability weighting using clinical trial registries
Ao Huang, Kosuke Morikawa, Tim Friede +1
Publication bias is a major concern in conducting systematic reviews and meta-analyses. Various sensitivity analysis or bias-correction methods have been developed based on selecti…
Improving the Power of Economic Experiments Using Adaptive Designs
Sebastian Jobjörnsson, Henning Schaak, Oliver Mußhoff +1
An important issue for many economic experiments is how the experimenter can ensure sufficient power for rejecting one or more hypotheses. Here, we apply methods developed mainly w…
Improving Adaptive Seamless Designs through Bayesian optimization
Jakob Richter, Tim Friede, Jörg Rahnenführer
We propose to use Bayesian optimization (BO) to improve the efficiency of the design selection process in clinical trials. BO is a method to optimize expensive black-box functions,…
Blinded sample size re-calculation in multiple composite population designs with normal data and baseline adjustments
Roland Gerard Gera, Tim Friede
The increasing interest in subpopulation analysis has led to the development of various new trial designs and analysis methods in the fields of personalized medicine and targeted t…
