get.matrix.Winv return the inverse matrix of W = V x C x V for the treatment of heteroscedastic and AR(1) errors see Wang (2011) section 5.3 for further details

Description

get.matrix.Winv return the inverse matrix of W = V x C x V for the treatment of heteroscedastic and AR(1) errors see Wang (2011) section 5.3 for further details

Usage

get.matrix.Winv(weight.hetero, nMO, nP, rho)

Arguments

weight.hetero	output of get.vec.weight.hetero
nMO	number of possible simulation chains (missing and non-missing)
nP	number of continuous predictors (e.g. future times)
rho	AR(1) correlation parameter in (-1,1)

Value

inverse matrix n x n of weights where coden is the total number of predictions (all the predictions for all the possible simulation chains)
