Bootstrap validity for the score test when instruments may be weak
(2009)
It is well-known that size adjustments based on bootstrapping the t-statistic perform poorly when instruments are weakly correlated with the endogenous explanatory variable. In this paper, we provide a theoretical proof ...
Bootstrap percolation on homogeneous trees has 2 phase transitions
(SPRINGER, 2008)
We study the threshold theta bootstrap percolation model on the homogeneous tree with degree b + 1, 2 <= theta <= b, and initial density p. It is known that there exists a nontrivial critical value for p, which we call ...
Robust bootstrap: an alternative to bootstrapping robust estimators
(Instituto Nacional de Estatística, 2014-06)
There is a vast literature on robust estimators, but in some situations it is still not easy to make inferences, such as confidence regions and hypothesis testing. This is mainly due to the following facts. On one hand, ...

Uma modificação da extensão do algoritmo AID para modelos lineares generalizados usando reamostragem Bootstrap
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2006-03-03)
One of the most frequently situation found by researchers is to find groups of similar individuals. The cluster analysis is a set of statistical techniques that identify mutually exclusive subgroups or classes over ...
