Abstract:

The univariate family of Topp-Leone distributions has been studied recently by a number of researchers. This distribution has finite support and possesses many interesting properties. In this article, we derive the exact distributions of X_1X_2, X_1/X_2 and X_1/(X_1+X_2) when X_1 and X_2 are independent Topp-Leone/beta variables. The resulting distributions are expressed in terms of special functions.
