ma.pred.wge {tswge}R Documentation

Predictive or rolling moving average

Description

Given a time series in the vector x and order (either an odd or even integer) ma.pred.wge computes a predictive moving average giving 1-step ahead predictions through x(n+1). Optionally, you can specify k-step ahead forecasts beyond the end of the data.

Usage

ma.pred.wge(x,order=3,n.ahead=1,plot=TRUE)

Arguments

x

Vector containing original realization

order

Order (odd or even integer) of moving average predictor (default=3)

n.ahead

Number of steps ahead to forecast beyond the end of the data (default=1)

plot

If plot=TRUE then plots of the data and moving average predictors are plotted

Value

x

Original data

pred

Data file showing 1-step ahead predictors up to x(k.ahead)

order

Order (odd or even integer) of the moving average predictor
