WebNov 16, 2015 · MCP-Mod involves pre-specifying candidate dose-reponse models followed by statistical testing for dose-response signal whilst controlling the type I error. The best … WebSince then, the methodology has been the subject of several investigations. Thomas and Wakana et al. investigated extensions to Bayesian methods for estimating or selecting the dose-response curve from a sparse dose design [14,15]. Klingenberg applied the MCP-Mod approach to proof-of-concept studies with binary responses [16].
