Further examples of GGC and HCM densities
Published 10 Dec 2013 in math.ST and stat.TH | (1312.2809v1)
Abstract: We display several examples of generalized gamma convoluted and hyperbolically completely monotone random variables related to positive $\alpha$-stable laws. We also obtain new factorizations for the latter, refining Kanter's and Pestana-Shanbhag-Sreehari's. These results give stronger credit to Bondesson's hypothesis that positive $\alpha$-stable densities are hyperbolically completely monotone whenever $\alpha\le1/2.$
