LTARpred {LTAR}

Forecast for a 3D Tensor Autoregression Model

Description

Using a historical 3D tensor, the LTARpred function will forecast h steps into the future.

Usage

LTARpred(p, tnsr, h, type = c("const", "trend", "both", "none"), season = NULL)

Arguments

p

: Number of time series lags

tnsr

: A 3D tensor

h

: Number of steps to forecast

type

Type of deterministic regressors to include.

season

: Inclusion of centered seasonal dummy variables (integer value of frequency).

Value

A Tensor-class object which contains the h step forecasts.
