information_arma | R Documentation |
Fortran implementation of InformationMatrixARMA
function of
FitARMA
package, except that the function uses the same
ARMA model definition as arima
, where both the
AR and MA parts of the model are on the right side of the equation, i.e.
MA coefficients differ in sign compared to InformationMatrixARMA
.
information_arma(phi = NULL, theta = NULL)
phi |
Autoregressive coefficients. |
theta |
Moving average coefficients. |
Large sample approximation of information matrix for ARMA process.
