Parametric bootstrap procedure

WebTo enable researchers to draw more robust conclusions, we introduce the MultiBERTs, a set of 25 BERT-Base checkpoints, trained with similar hyper-parameters as the original BERT model but differing in random weight initialization and shuffling of training data. We also define the Multi-Bootstrap, a non-parametric bootstrap method for ... Webthis work employs, in a empirical study, the bootstrap procedure in three different ways (bootstrap in the observations, conditional bootstrap and the bootstrap in the residuals) in the interval inference of the parameters, comparing two bootstrap methods of building confidence intervals – percentile bootstrap and bootstrap with bias correction.
