This function creates the theoretical co-variance matrix for the multivariate normal distribution which is used to model the liabilities.

Usage

covmatrix(h2, n_sib = 0)

Arguments

h2

Number specifying heritability parameter.

n_sib

Integer specifying number of siblings (default 0).

Value

A co-variance matrix, created from the value of h2 and the number of sibs.
