marlsq {TSSS}

Least Squares Method for Multivariate AR Model

Description

Fit a multivariate AR model by least squares method.

Usage

marlsq(y, lag = NULL)

Arguments

y

a multivariate time series.

lag

highest AR order. Default is 2 \sqrt{n}, where n is the length of the time series y.

Value

An object of class "marlsq", which is a list with the following components:

maice.order

order of the MAICE model.

aic

AIC of the MAR model with minimum AIC orders.

v

innovation covariance matrix.

arcoef

AR coefficient matrices.
