摘要:It is a great pleasure for me to make available to you the first number of Volume 4 of the Chilean Journal of Statistics, published by the Chilean Statistical Society. Seven papers are included in this issue. These papers cover the following topics: Estimation methods for the population mean using auxiliary information and L-statistics based on random vectors with multivariate elliptical distributions, goodness-of-fit tests, reconstruction of chaotic dynamic systems using non-linear filters, Bayesian reference analysis for the Poisson-exponential lifetime distribution, and a study of exponential-type tails applied to Birnbaum-Saunders models. I would like to thank the researchers and internationally renowned statisticians who have honored us by choosing our young journal to publish some of their research.
