Griddy Gibbs update for dyadic correlation

Description

Simulation of dyadic correlation from its approximate full conditional distribution using griddy Gibbs sampling

Usage

rrho_fc(Z, Sab, s2 = 1, offset = 0, ngp = 100, asp = NULL)

Arguments

Z

n X n normal relational matrix

Sab

covariance of additive effects

s2

residual variance

offset

matrix of the same dimension as Z. It is assumed that Z-offset follows an SRM distribution, so the offset should contain any regression terms and multiplicative effects (such as Xbeta(X,beta+ U%*%t(V) )

ngp

the number of points for an unevenly-spaced grid on which to approximate the full conditional distribution

asp

use arc sine prior (TRUE) or uniform prior (FALSE)

Value

a value of rho
