AutoSEARCH (version 1.3)

AutoSEARCH-package: General-to-Specific (GETS) Model selection

Description

Automated multi-path GETS model selection of either an AR-X model with log-ARCH-X errors, or of a log-ARCH-X model of the error. NOTE: The package has been succeeded by the package gets, also available on the CRAN, which is intended to be more user-friendly, faster and easier to extend. AutoSEARCH will continue to be maintained, but the development focus will switch to gets. Users are therefore encouraged to consider gets instead.

Examples

#Generate from AR(1) model:
set.seed(123)
y <- arima.sim(list(ar=0.4), 200)

#Estimate AR(2) with intercept as mean specification
#and log-ARCH(4) as log-volatility specification:
sm(y, mc=TRUE, ar=1:2, arch=1:4)

#General-to-Specific model selection of the mean:
mymodel <- gets.mean(y, mc=TRUE, ar=1:2, arch=1:4)

#General-to-Specific model selection of the
#simplified mean specification:
gets.vol(mymodel$resids, arch=1:4)
