cor2psi {binarySimCLF}R Documentation

From Correlation To Pairwise Odds-Raio

Description

This function converts a correlation matrix associated with a mean vector into a vector of pairwise odds ratio. This is done in the following order. Let μ = (μ_1, μ_2, ..., μ_n). Then the odds ratio vector is of length n choose 2 with elements psi_{12}, psi_{13}, ..., psi_{1n}, psi_{23}, ..., psi_{(n-1)n} .

Usage

cor2psi(r, mu)

Arguments

r Correlation matrix.
mu Mean vector.

Value

Returns a list with two components:

psi The pairwise odds ratio vector if the routine executes without error.
error A logical; if TRUE then an error has occurred. This usually means that division by zero has occured.
