Using the different construction for gamma (F) based 'asymptotically self-similar activity time' processes with long-range dependence from Fin- lay and Seneta (2006) we extend the constructions for inverse-gamma and gamma based 'asymptotically self- similar activity time' processes with integer-vMued parameters and long-range dependence in Heyde and Leo- nenko (2005) and Finlay and Seneta (2006) to noninteger-valued parameters.展开更多
