“…Siaw et al . (2011) define the generalized ( a , b ,1) family , the difference being that the recursion (5) starts at n = 2, and the parameters are A , B , P 1 and p 0 , while the matrix P 0 becomes irrelevant. The PH ( α , T ) distribution belongs to the generalized ( a , b ,1) family, with A = T , B = 0, , and .…”
