For estimating the variance of nonlinear statistics like regression and correlation coefficients in stratified sampling designs, the Balanced Repeated Replication (BRR) method has received special attention, although other procedures like linearization (Taylor’s series expansion method), Jackknife repeated replications and the Bootstrap method are also available in the literature. BRR method in...

We consider the Useful Informational Energy introduced by L. Pardo [5]. Our purpose is to study the asymptotic distribution of its analogue estimator, in a random and stratified sampling, as well as its application to testing hypotheses.

Stratified sampling is often used in opinion polls to reduce standard errors, and it is known as variance reduction technique in sampling theory. The most common approach of resampling method is based on bootstrapping the dataset with replacement. A main purpose of this work is to investigate extensions of the resampling methods in classification problems, specifically we use decision trees, fr...
