scale_gmrf_precision: Scale of GMRF precision matrix
In mrc-ide/naomi: Naomi Model for Subnational HIV Estimates
scale_gmrf_precision R Documentation
Scale of GMRF precision matrix
Description
This function scales the precision matrix of a GMRF such that the geometric
mean of the marginal variance is one.
Usage
scale_gmrf_precision(
Q,
A = matrix(1, ncol = ncol(Q)),
eps = sqrt(.Machine$double.eps)
)
Arguments
Q
Precision matrix for a GMRF.
A
Linear constraint for Q.
eps
Value of the small constant added to the diagonal of Q for
invertibility.
Details
This implements the same thing as INLA::inla.scale.model. The marginal
variance of each connected component is one.
