Calculate absolute values of the eigenvalues of the "bold A" matrices containing the AR coefficients

Description

get_boldA_eigens calculates absolute values of the eigenvalues of the "bold A" matrices containing the AR coefficients for each regime.

Usage

get_boldA_eigens(stvar)

Arguments

stvar

object of class "stvar"

Value

Returns a matrix with d*p rows and M columns - one column for each regime. The mth column contains the absolute values (or modulus) of the eigenvalues of the "bold A" matrix containing the AR coefficients correspinding to regime m.
