Methods for filterPolyCoef
in package sarima.
Methods
The filterPolyCoef
methods return results with the same
structure as the corresponding methods for filterPoly
but with
polynomials replaced by their coefficients. If lag_0
is
FALSE
the order 0 coefficients are dropped.
signature(object = "VirtualBJFilter")
Calls
filterCoef(object)
, negates the result and prepends 1 iflag_0
isTRUE
.signature(object = "VirtualSPFilter")
Calls
filterCoef(object)
and prepends 1 to the result iflag_0
isTRUE
.signature(object = "VirtualArmaFilter")
Returns a list with the following components:
- ar
coefficients of the autoregression polynomial.
- ma
coefficients of the moving average polynomial.
signature(object = "BJFilter")
The coefficients of a polynomial whose coefficients are the negated filter coefficients. This is equivalent to the method for "VirtualBJFilter" but somewhat more efficient.
signature(object = "SPFilter")
The coefficients of a polynomial whose coefficients are as stored in the object. This is equivalent to the method for "VirtualSPFilter" but somewhat more efficient.
signature(object = "SarimaFilter")
Returns a list with the same components as the "SarimaFilter" method for
filterPoly
, where the polynomials are replaced by their coefficients.
