best_glp_models {artfima}

Best AIC/BIC Models for Specified GLP

Description

This function is used by bestModels

Usage

best_glp_models(z, glp = c("ARTFIMA", "ARFIMA", "ARIMA"), p = 2, q = 2, 
   likAlg = c("exact", "Whittle"), d=0, ...)

Arguments

z

time series

glp

glp is equal to one of the following choices: "ARTFIMA", "ARFIMA" or "ARIMA"

p

maximum order of AR component

q

maximum order of MA component

likAlg

likAlg = c("exact", "Whittle")) either "exact" or "Whittle"

d

regular integer differencing parameter

...

optional arguments for artfima such as lambdaMax

Value

A list with 4 entries:

LL

log-likelihood of models

artfima_time

total time

aic

list with best aic models

bic

list with best bic models

Each of the components aic and bic is a list with three components:

bestaic

best aic models

bestbicModel

best model

aic

plausability

Similarly for the bic component.
