testRmACD:
LM test of no Remaining ACD (Meitz and Terasvirta, 2006)
Description
Tests if there is any remaining ACD structure in the residuals
Usage
testRmACD(fitModel, pStar = 2, robust = TRUE)
Arguments
fitModel
a fitted ACD model, i.e. an object of class "acdFit".
pStar
robust
if TRUE the LM statistic will be calculated using the "robust" version, making its asymptotic behavior unaffected by possible misspecification of the error term distribution (Meitz and Terasvirta, 2006).
Value
a list of:
chi2
the value of the LM statistic.
pv
the pvalue of the test statistic.
Details
For the model
the function tests the null hypothesis
