warn_eigens: Warn about near-unit-roots in some regimes
Description
warn_ar_roots warns if the model contains near-unit-roots in some regimes
Usage
warn_eigens(gmvar, tol = 0.002)
Arguments
gmvar
an object of class 'gmvar' created with fitGMVAR or GMVAR.
tol
if eigenvalue is closer than tol to its bound, a warning is thrown
Value
Doesn't return anything.
Details
Warns if, for some regime, some moduli of "bold A" eigenvalues are larger than 1 - tol or
some eigenvalue of the error term covariance matrix is smaller than tol.
