Confidence Intervals of Gini Coefficient Under Unequal Probability Sampling

Distribution Free Confidence Intervals for Quantiles Based on Extreme Order Statistics in a Multi-Sampling Plan

Extended Abstract. Let Xi1 ,..., Xini   ,i=1,2,3,....,k  be independent random samples from distribution $F^{alpha_i}$،  i=1,...,k, where F is an absolutely continuous distribution function and $alpha_i>0$ Also, suppose that these samples are independent. Let Mi,ni and  M'i,ni  respectively, denote the maximum and minimum of the ith sa...

Performance Evaluation of Confidence Intervals for Ordinal Coefficient Alpha

Confidence Intervals for Omega Coefficient: Proposal for Calculus.

La confiabilidad es entendida como una propiedad métrica de las puntuaciones de un instrumento de medida. Recientemente se viene utilizando el coeficiente omega (ω) para la estimación de la confiabilidad. No obstante, la medición nunca es exacta por la influencia del error aleatorio, por esa razón es necesario calcular y reportar el intervalo de confianza (IC) que permite encontrar en valor ver...

An Empirical Study of some Unequal Probability Sampling Estimators

An empirical study has been carried out to decide about the performance of various estimators used in unequal probability sampling without replacement and a sample of size 2. The Hansen–Hurwitz estimator and simple random sampling method has also been compared in this study. Some suggestions have been given at the end.
