Function for computing the ARMA(p, q) conditional likelihood Models with AR component: zt are from t = p + 1 to m Models with MA component: eps_0 = ... = eps_q+1 = 0 The input zt should be FCFZ, i.e., data corrected in freq. domain then IFTd FCFZ should be FCFZ[-c(1, n)]; i.e., have removed elements 1 and n beforehand No sigma2 in here anymore! ...: Further arguments to be passed to likelihood function
