SOME UNIFIED RESULTS ON COMPARING LINEAR COMBINATIONS OF INDEPENDENT GAMMA RANDOM VARIABLES
2012
Probability in the engineering and informational sciences (Print)
2012). Some unified results on comparing linear combinations of independent gamma random variables. Probability in the Engineering and Informational Sciences, 26, pp 393-404. In this paper, a new sufficient condition for comparing linear combinations of independent gamma random variables according to star ordering is given. This unifies some of the newly proved results on this problem. Equivalent characterizations between various stochastic orders are established by utilizing the new condition.
