psiPrelec: psiPrelec

In dlandy/WarpedBayes: Implements Design Pattern Discussed in Landy, Crawford, & Corbin

Description

This function is a transformation function that takes the log of the log of the inverse (which can be used to generate the Prelec functions). By design, it is robust to the inclusion of the occasional 0, which it maps to a very small value, which can optionally be specified It's appropriate for mapping (0, 1):-> (-inf, inf).

Usage

psiPrelec(stimuli, smallValue = 10^-30)

Arguments

stimuli	a vector of positive stimuli, between 0 and inf
smallValue	A value to set nominal 0's to, to avoid errors in plotting simulated data, or aberrant responses

Value

a vector containing "warped" stimuli

(0:1000/1000) %>% psiPrelec() %>% vanillaBayes() %>% psiPrelecInverse()  # Implements Prelec, 1998
