命令简介

The E-value is an alternative approach to sensitivity analyses for unmeasured confounding in observational studies that avoids making assumptions that, in turn, require subjective assignment of inputs for some formulas. Specifically, an E-value analysis asks the question: how strong would the unmeasured confounding have to be to negate the observed results?
