GARCHselection {ConnectednessApproach} | R Documentation |
Univariate GARCH selection criterion
Description
This function estimates and evaluates a combination of GARCH models with different distributions and suggests the best GARCH models among all alternatives given some test statistics
Usage
GARCHselection(
x,
distributions = c("norm", "snorm", "std", "sstd", "ged", "sged"),
models = c("sGARCH", "eGARCH", "gjrGARCH", "iGARCH", "TGARCH", "AVGARCH", "NGARCH",
"NAGARCH", "APARCH", "ALLGARCH"),
prob = 0.05,
conf.level = 0.9,
lag = 20,
ar = 0,
ma = 0
)
