Distribution of the ratio of geometric mean to arithmetic mean in a sample from a two-piece double exponential distribution. (English) Zbl 0746.62010
Summary: This paper deals with the distribution of the ratio of the geometric mean to the arithmetic in a sample drawn from a two-piece double exponential distribution, where two pieces have different scale parameters. For this purpose, hypergeometric functions are utilized and this distribution is expressed in terms of Meijer’s \(G\)-function.
