Researchers have developed a novel amortized inference method using neural networks to estimate sampling distributions, particularly for scenarios where the traditional Efron's bootstrap method fails. This new approach, trained on simulated data and utilizing a pinball loss function, can generate full sampling distribution estimates from a single dataset with high accuracy. The method demonstrates superior performance compared to classical techniques like the m-out-of-n bootstrap and subsampling across various challenging statistical problems, including estimating extreme quantiles and tail indices.
