SF.DR {sufficientForecasting}

Directional regression for sufficient forecasting

Description

Directional regression for sufficient forecasting

Usage

SF.DR(y, X, newX = NULL, K = "default", L = 1, etaopg = "default", nslices = 3)

Arguments

y

Response, T by 1 matrix

X

Predictors, p by T matrix

newX

New predictors, a vector contains p entries (or NULL)

K

The number of common factors (default = obtained by getK)

L

The number of predictive indices, L is required to be no greater than K (default = 1)

etaopg

hyperparameter in DR (default = obtained by opg)

nslices

hyperparameter in DR (default = 3)

Value

Out-of-sample forecast for newX; or in-sample forecast for the last observed data point if newX is NULL
