The exact distribution of the ratio X/Y is derived when X and Y are gamma and Levy random variables distributed independently of each other. Extensive tabulations of the associated percentage points are also given.

It is shown that the total amount of income earned during a reference period can be expressed as the products of components of bivariate Pareto distributions. The exact distribution of the total amount of income P = XY and the corresponding moment properties are derived when (X, Y ) follows...

Measurement error can impact estimator precision, obscure estimated relationships between variables, and distort the estimated intertemporal behavior of important economic characteristics. A commonly known model for measurement error assumes that measured income is the product of true income and...

Various q-type distributions have appeared in the physics literature in the recent years, see e.g. L.C. Malacarne, R.S. Mendes, E. K. Lenzi, q-exponential distribution in urban agglomeration, Phys. Rev. E 65, (2002) 017106. S.M.D. Queiros, On a possible dynamical scenario leading to a...

The exact distribution of visiting rates does not appear to be widely known in the marketing literature. Here, analytical expressions are derived for the exact distribution, and their performance is compared with some known approximation. Some computer programs are provided for practical use.
