Closed Expression for Characteristic Function of CEPE Distribution

Tibor K Pogany


The recent paper by Maturi and Elsayigh [The Correlation between Variate-Values and Ranks in Samples from Complete
Fourth Power Exponential Distribution, Journal of Mathematics Research 1 (2009), No. 1, 14–18] contains an expression
for the chatacteristic function of CFPE distribution in the §2 as double sum (one infinite) of terms involving special
functions. Here, I would like to point that this formula turns out to be a corollary of closed form expression for the
characteristic function of so–called Complete Eventh Power Exponential (CEPE) distribution.
