Calculate regime means \mu_{m}

Description

get_regime_means calculates regime means \mu_{m} = (I - \sum A_{m,i})^(-1)) for the given GMVAR, StMVAR, or G-StMVAR model.

Usage

get_regime_means(gsmvar)

Arguments

gsmvar

an object of class 'gsmvar', typically created with fitGSMVAR or GSMVAR.

Value

Returns a (dxM) matrix containing regime mean \mu_{m} in the m:th column, m=1,..,M.
