Müller, Alfred; Scarsini, Marco - In: Journal of Multivariate Analysis 73 (2000) 1, pp. 107-119

In this paper we solve two open problems posed by Joe (1997) concerning the supermodular order. First we give an example which shows that the supermodular order is strictly stronger than the concordance order for dimension d=3. Second we show that the supermodular order fulfils all desirable...

L-superadditive function and its integral transform that preserves Schur property

Gopal, G.; Rajalakshmi, S. - In: Statistics & Probability Letters 45 (1999) 3, pp. 191-194

L-superadditive functions find many applications in rearrangement inequalities, operations research and reliability. In … this paper, we prove a theorem of integral transforms for L-superadditive functions that preserve Schur property. …
