Simultaneous inference of correlated marginal tests using intersection-union or union-intersection test principle
Ludwig A. Hothorn
Two main approaches in simultaneous inference are intersection-union tests and union-intersection tests. For intersection-union hypotheses, the classical IUT based on marginal p-va…
Closed testing procedures for treatment-versus-control comparisons and multiple correlated endpoint
Ludwig A. Hothorn, Siegfried Kropf
Preferably in two- or three-arm randomized clinical trials, a few (2,3) correlated multiple primary endpoints are considered. In addition to the closed testing principle based on d…
Simultaneous comparisons of treatments versus control (Dunnett-type tests) for location-scale alternatives
Ludwig A. Hothorn
Commonly, the comparisons of treatment groups versus a control is performed for location effects only where possible scale effects are considered as disturbing. Sometimes scale eff…
A statistical method for estimating the no-observed-adverse-event-level
Ludwig A. Hothorn
In toxicological risk assessment the benchmark dose (BMD) is recommended instead of the no-observed-adverse effect-level (NOAEL). Still a simple test procedure to estimate NOAEL is…
