Paired bootstrap resampling
WebFeb 10, 2024 · Model selection is an important and challenging problem in statistics. The model selection is inevitable in a large number of applications including life sciences, social sciences, business, or economics. In this article, we propose a resampling-based information criterion called paired bootstrap criterion (PBC) for model selection. WebNov 27, 2015 · In your case the original data is pairs of data. So to do a bootstrap, you would have to random sample (with replacement) on the pairs of the original data. That is equivalent to do the bootstrap on the difference scores and performing the effect size …
