PoisNonNor (version 1.6.1)

intercor.PP: Computes the subset of the intermediate correlation matrix that is pertinent to the count pairs

Description

This function computes the submatrix of the intermediate correlation matrix of the multivariate normal distribution. It is relevant to the count part of the data.

Usage

intercor.PP(lamvec, cmat)

Arguments

lamvec

a vector of lambda values of length n1.

cmat

a n1xn1 matrix of specified correlations.

Value

Returns an intermediate matrix of size n1xn1.

Details

Calculations are done by combining the methods described in Yahav and Shumeli (2012) and Amatya and Demirtas (2017).
