MTSdiag: Multivariate Time Series Diagnostic Checking

Description Usage Arguments Value Author(s) Examples

Description

Performs model checking for a fitted multivariate time series model, including residual cross-correlation matrices, multivariate Ljung-Box tests for residuals, and residual plots

Usage

1
MTSdiag(model, gof = 24, adj = 0, level = F)

Arguments

model

A fitted multivariate time series model

gof

The number of lags of residual cross-correlation matrices used in the tests

adj

The adjustment for degrees of freedom of Ljung-Box statistics. Typically, the number of fitted coefficients of the model. Default is zero.

level

Logical switch for printing residual cross-correlation matrices

Value

Various test statistics, their p-values, and residual plots.
