quality_ratio: Compute the logit of the ratio of qualities

In BSBT: The Bayesian Spatial Bradley--Terry Model

Compute the logit of the ratio of qualities

Description

This function computes the probability i beats j on the logit scale. It is given by logit(pi_ij) = lambda_i - log(exp(lambda_i) + exp(lambda_j))

Usage

quality_ratio(x, y)

Arguments

x	The level of deprivation of the winning object on the exponential scale
y	The level of deprivation of the losing object on the exponential scale

Value

logit(pi_ij)

Examples

#compare areas with levels -2 and 2

qr <- quality_ratio(exp(-2), exp(2))
