rUV_fc: Gibbs sampling of U and V

In amen: Additive and Multiplicative Effects Models for Networks and Relational Data

Gibbs sampling of U and V

Description

A Gibbs sampler for updating the multiplicative effect matrices U and V

Usage

rUV_fc(Z, U, V, Suv, rho, s2 = 1, offset = 0)

Arguments

Z	n X n normal relational matrix
U	current value of U
V	current value of V
Suv	covariance of (U V)
rho	dyadic correlation
s2	dyadic variance
offset	a matrix of the same dimension as Z. It is assumed that Z-offset is equal to the multiplicative effects plus dyadic noise, so the offset should contain any additive effects (such as Xbeta(X,beta+ outer(a,b,"+") )

Value

U	a new value of U
V	a new value of V
