Hi I tried to calculate modified Diebold-Mariano Test in R . I have already find a "forecast" package to calculate the Diebold-Mariano Test. Please let me know how to obtain " Modified Diebold-Mariano Test" ?

I created a EM algorithm for Generalized hyperbolic distribution. I want to estimate mutheldaplus, sigmatheldaplus, betasigmaplus in my code. After getting use these value , then my iteration have to be begin of this code. But I can not to do iteration part. Can you help me use my code and get iteration ? Do know any useful code for EM algorithm for Generalized Hyperbolic library(QRMlib)

My code: spec<-ugarchspec(variance.model = list(model = "sGARCH", garchOrder = c(1, 1), submodel = "Null", external.regressors = NULL, variance.targeting = FALSE), mean.model = list(armaOrder=c(0,0),include.mean =FALSE, archm = FALSE, archpow = 1, arfima = FALSE, external.regressors = NULL, archex = FALSE), distribution.model = "norm", start.pars = list(),
