This paper shows that linear functions of order statistics (L-statistics) based on random samples have a Fundamental Skew distribution (Arellano-Valle Genton, 2003). The paper also examines the exact distribution of L-statistics when the sampled population is Skew Normal. Exact distributions of...

An estimator of the correlation between Italian and U.S. Stock Returns is introduced. The properties of the estimator are invariant with respect to a wide class of GARCH models. The empirical evidence shows the existence of a positive correlation between Italian an U. S. stock returns.

The Gini concentration ratio has been extensively used in the study of "inequality" of distributions. According to Chakrabarthy (1982), "the Lorenz curve and the Gini index have remained the most popular and powerful tool in the analyses of size distribution of income". A major statistical...
