warn_eigens function

Warn about near-unit-roots in some regimes

warn_eigens warns if the model contains near-unit-roots in some regimes

warn_eigens(stvar, tol = 0.002, allow_unstab = FALSE)

Arguments

• stvar: object of class "stvar"
• tol: if eigenvalue is closer than tol to its bound, a warning is thrown
• allow_unstab: If TRUE, estimates not satisfying the stability condition are allowed. Always FALSE if weight_function="relative_dens".

Returns

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.
