Hybrid of the scatter search, improved adaptive genetic, and expectation maximization algorithms for phase-type distribution fitting

Although a large number of different methods for establishing the fitting parameters of PH distributions to data traces (PH fitting) have been developed, most of these approaches lack efficiency and numerical stability. In the present paper, a restricted class of PH distribution, called the hyper-Er...
