mat.arma {dae}R Documentation

Forms an arma correlation matrix

Description

Form the correlation matrix of order order whose correlations follow the arma pattern. The resulting matrix is banded.

Usage

mat.arma(ARparameter, MAparameter, order)

Arguments

ARparameter

A numeric value for the autoregressive parameter of the process, being the weight given to the lag 1 response values.

MAparameter

A numeric value for the moving average parameter of the process, being the weight given to the lag 1 random variable.

order

The order of the matrix to be formed.

Details

The correlations in the correlation matrix, corr say, are calculated from the correlation parameters, ARparameters. The values in

Value

A banded correlation matrix whose elements follow an arma pattern.
