Int.Corr.NN {BinNonNor}

Computes an intermediate correlation matrix for continuous non-normal variables given the specified correlation matrix

Description

This function computes the intermediate correlation matrix for continuous non-normal-continuous non-normal combinations as formulated in Demirtas et al. (2012).

Usage

Int.Corr.NN(n.NN, corr.vec = NULL, corr.mat = NULL, coef.mat)

Arguments

n.NN

Number of continuous non-normal variables.

corr.vec

Vector of elements below the diagonal of correlation matrix ordered columnwise.

corr.mat

Specified correlation matrix.

coef.mat

Matrix of coefficients produced from fleishman.coef.

Value

A correlation matrix of size n.NN*n.NN.
