Stine.Shaman {BootPR}R Documentation

bias-corrected estimation based on Shaman-Stine formula

Description

The function returns parameter estimates and bias-corrected forecasts using Shaman and Stine bias formula for univariate AR models

Usage

Stine.Shaman(x, p, h, type, correct)

Arguments

x a time series data set
p AR order
h the number of forecast period
type "const" for the AR model with intercept only, "const+trend" for the AR model with intercept and trend
correct "kilian" for Kilian's stationarity-correction; "ssf" for stationarity-correction based on stable spectral factorization

Value

coef Bias-corrected parameter estimates using Shama-Stine formula
resid residuals
forecast point forecasts from bias-corrected parameter estimates

Note

Contact the author for the details of the stationarity-correction based on stable spectral factorization
