Evaluation of incidence rates in pre-clinical studies using a williams-type procedure

Hothorn, Ludwig A.; Sill, Martin; Schaarschmidt, Frank (Berlin : De Gruyter, 2010)

The analysis of dose-response relationships is a common problem in pre-clinical studies. For example, proportions such as mortality rates and histopathological findings are of particular interest in repeated toxicity ...
Optimization of PEG-salt aqueous two-phase systems by design of experiments

Glyk, Anna; Solle, Dörte; Scheper, Thomas; Beutel, Sascha (Amsterdam : Elsevier, 2015)

Since the mechanism governing the partitioning behavior of biomolecules, such as proteins and enzymes, in polyethylene glycol (PEG)-salt aqueous two-phase systems (ATPS) is complex and not easily predictable, many laborious ...
Trend tests for the evaluation of exposure-response relationships in epidemiological exposure studies

Hothorn, Ludwig A.; Vaeth, Michael; Hothorn, Torsten (London : BioMed Central Ltd., 2009)

One possibility for the statistical evaluation of trends in epidemiological exposure studies is the use of a trend test for data organized in a 2 × k contingency table. Commonly, the exposure data are naturally grouped or ...
