Probability weighting function
WebbIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events (subsets of the sample space)..

WebbCalculations for inverse probability of censoring weights (IPCW) Source: R/ipcw.R. The method of Graf et al (1999) is used to compute weights at specific evaluation times that can be used to help measure a model's time-dependent performance (e.g. the time-dependent Brier score or the area under the ROC curve). This is an internal function. WebbDrazen Prelec, 1998. "The Probability Weighting Function," Econometrica, Econometric Society, vol. 66(3), pages 497-528, May.

Webb24 sep. 2024 · In prospect theory, the probability weighting functions are defined as follows (Wakker 2010 ). Definition 2 The function w: [0,1] \rightarrow [0,1] is said to be a probability weighting function, if w satisfies the following requirements: (1) w is strictly increasing; (2) w (0)=0 and w (1)=1.
