Friday and Patil's Bivariate Exponential Distribution with Application to Drought Data

Nadarajah, Saralees; Gupta, Arjun - In: Water Resources Management 20 (2006) 5, pp. 749-759

Motivated by hydrological applications, we derive the exact distributions of R=X + Y, P=XY and W=X/(X+Y) and the corresponding moment properties when X and Y follow Friday and Patil's bivariate exponential distribution. An application of the results is provided to drought data from Nebraska....
