emd.pred {EMD}

Prediction by EMD and VAR model

Description

This function calculates prediction values and confidence limits using EMD and VAR (vector autoregressive) model.

Usage

Arguments

varpred

prediction result of IMF's by VAR model.

trendpred

prediction result of residue by polynomial regression model.

ci

confidence interval level.

figure

specifies whether prediction result is displayed.
