Saralees Nadarajah, B. M. Golam Kibria Applicationes Mathematicae 33 (2006), 185-193 MSC: 33C90, 62E99. DOI: 10.4064/am33-2-4


Burr distributions are some of the most versatile distributions in statistics. In this paper, a drought application is described by deriving the exact distributions of $U = X Y$ and $W = X/(X+Y)$ when $X$ and $Y$ are independent Burr XII random variables. Drought data from the State of Nebraska are used.
