BOOTSTRAP SAMPLING IS WITH REPLACEMENT: A COMMENT ON AYLLN ET AL. (2011)

摘要

The bootstrap can be used to estimate confidence intervals for complex statistics such as weighted usable area, the habitat index calculated by the Physical Habitat Simulation System (PHABSIM) and related models. Use of the bootstrap entails sampling with replacement from the original sample, such as a set of PHABSIM transects. Because the method has been improperly applied to PHABSIM transects in several instances, I explain in detail why bootstrap sampling is with replacement. Copyright (c) 2011 John Wiley Sons, Ltd.
