Evaluation of a multiple integral of Tefera via properties of the exponential distribution
The electronic journal of combinatorics, Tome 15 (2008)
An interesting integral originally obtained by Tefera ("A multiple integral evaluation inspired by the multi-WZ method," Electron. J. Combin., 1999, #N2) via the WZ method is proved using calculus and basic probability. General recursions for a class of such integrals are derived and associated combinatorial identities are mentioned.
