The fundamental bootstrap assumption is that the bootstrap approximates reality; that the sampling distribution of a statistic under the empirical distribution F̂ approximates the sampling distribution under the true (unknown) distribution. A natural way to test this is to investigate how the bootstrap distribution varies when F̂ is replaced by other distributions. Iterated bootstrapping, jackkni...
We use amortized inference in conjunction with implicit models to approximate the bootstrap distribution over model parameters. We call this the amortized bootstrap, as statistical strength is shared across dataset replicates through a metamodel. At test time, we can then perform amortized bagging by drawing multiple samples from the implicit model. We find amortized bagging outperforms bagging...
Introduction: Previously, 186Re and 188Re radioisotopes have been produced through appropriate activities, and each of them has been used for therapeutic applications. The 186Re and 188Re have unique properties, which make them proper for the treatment of tumors in different sizes. The long-range 188Re, is suitabl...
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...

The statistical properties of sample estimation and bootstrap estimation of phylogenetic variability from a sample of nucleotide sequences are studied by using model trees of three taxa with an outgroup and by assuming a constant rate of nucleotide substitution. The maximum-parsimony method of tree reconstruction is used. An analytic formula is derived for estimating the sequence length that is...
