Simple Nonparametric Inference for Monotonic Processes
Authors:M. Schemper
Abstract:A scoring system for possibly censored monotonic processes is presented which allows to analyze such processes by means of standard parametric or nonparametric tests. In either case the analyses are invariant to monotonic transformations of time. Such analyses are of relevance whenever changes in degree of function are observed rather than the single and 100% loss of function of survival analysis. An example of gradually increasing function after particular reconstructive surgery is supplied.
Keywords:Competing risks  Monotonic process  Nonparametric test  Survival analysis  Rank transform
