Informative Simultaneous Confidence Intervals for Graphical Test Procedures
Werner Brannath, Liane Kluge, Martin Scharpenberg
Simultaneous confidence intervals (SCIs) that are compatible with a given closed test procedure are often non-informative. More precisely, for a one-sided null hypothesis, the boun…
Optimal monotone conditional error functions
Werner Brannath, Johanna zur Verth, Morten Dreher +1
This paper presents a general method that provides optimal monotone conditional error functions for confirmatory adaptive two-stage designs with conditional power based sample size…
Simultaneous confidence intervals for an extended Koch-Röhmel design in three-arm non-inferiority trials
Martin Scharpenberg, Werner Brannath
Three-arm `gold-standard' non-inferiority trials are recommended for indications where only unstable reference treatments are available and the use of a placebo group can be justif…
Single-stage, three-arm, adaptive test strategies for non-inferiority trials with an unstable reference
Werner Brannath, Martin Scharpenberg, Sylvia Schmidt
For indications where only unstable reference treatments are available and use of placebo is ethically justified, three-arm `gold standard' designs with an experimental, reference…
Interpretation of Linear Regression Coefficients under Mean Model Miss-Specification
Werner Brannath, Martin Scharpenberg
Linear regression is a frequently used tool in statistics, however, its validity and interpretability relies on strong model assumptions. While robust estimates of the coefficients…
