Los métodos estadísticos basados en muestreo de rango ordenado a menudo
son una considerable mejora que el muestreo aleatorio simple. La medida de
entropía ha sido influencial en el desarrollo de medidas de ajuste de modelos
paramétricos. Este artículo propone pruebas de bondad de ajuste de la
distribución Laplace basada en la entropía muestral cuando se usan estructuras
basadas en muestras de rango ordenado. Para cada diseño, los valores
críticos del correspondiente estadístico de prueba son estimados por medio
de simulaciones para diferentes tamaños de muestra. Un estudio de Monte
Carlo de la potencia de los nuevos tests es implementado para diferentes distribuciones
alternas y tamaños de muestra con el fin de comparar el método
propuesto con otros disponibles. La simulación muestra que el muestreo de
rango ordenado y sus variaciones brindan mayor potencia que los métodos
basados en muestreo aleatorio simple
Statistical methods based on ranked set sampling (RSS) often lead to
marked improvement over analogous methods based on simple random sampling
(SRS). Entropy has been influential in the development of measures of
fit of parametric models to the data. This article develops goodness-of-fit
tests of the Laplace distribution based on sample entropy when data are collected
according to some RSS-based schemes. For each design, critical values
of the corresponding test statistic are estimated, by means of simulation, for
some sample sizes. A Monte Carlo study on the power of the new tests is
performed for several alternative distributions and sample sizes in order to
compare our proposal with available method in SRS. Simulation results show
that RSS and its variations lead to tests giving higher power than the test
based on SRS.
