tetrachoric: Estimate parameters from odds-ratio

In kkholst/mets: Analysis of Multivariate Event Times

Estimate parameters from odds-ratio

Description

Calculate tetrachoric correlation of probabilities from odds-ratio

Usage

tetrachoric(P, OR, approx = 0, ...)

Arguments

P	Joint probabilities or marginals (if OR is given)
OR	Odds-ratio
approx	If TRUE an approximation of the tetrachoric correlation is used
...	Additional arguments

Examples

tetrachoric(0.3,1.25) # Marginal p1=p2=0.3, OR=2
P <- matrix(c(0.1,0.2,0.2,0.5),2)
prod(diag(P))/prod(lava::revdiag(P))
##mets:::assoc(P)
tetrachoric(P)
or2prob(2,0.1)
or2prob(2,c(0.1,0.2))
