rs2_fc {amen}

Gibbs update for dyadic variance

Description

Gibbs update for dyadic variance

Usage

rs2_fc(Z, rho,offset=0,nu0=NULL,s20=NULL)

Arguments

Z

n X n normal relational matrix

rho

current value of rho

offset

matrix of the same dimension as Z. It is assumed that Z-offset is equal to dyadic noise, so the offset should contain any additive and multiplicative effects (such as Xbeta(X,beta+ U%*%t(V) + outer(a,b,"+") )

nu0

prior degrees of freedom

s20

prior estimate of s2

Value

a new value of s2
