Abstract:

Let {X_{i};i=1,2,...,K} represent K continuous random variables and let T be the set of all possible permutations of the first K integers. Then P(X_{i1}< X_{i2}< ...< X_{ik}) is a precedence probability if {i1,i2,...,ik} belongs to T. We define two index measures for separation or similarity among these K distributions based on the precedence probabilities. The properties and usage of these index measures will be discussed.
