Robust confidence interval
WebDec 23, 2014 · We propose new theory-based, more robust confidence interval estimators for average treatment effects at the cutoff in sharp RD, sharp kink RD, fuzzy RD, and fuzzy kink RD designs. Our proposed confidence intervals are constructed using a bias-corrected RD estimator together with a novel standard error estimator. WebTheir results indicate that 1-α 100 % confidence interval for ρ provide fairly accurate coverage when a robust correlation measure is used [43, 44]. For one sided confidence limits, simply replace α 2 by α in the equation for L C L · or U C L ·. Alternative methods, such as bootstrapping, are also available for calculating confidence ...

WebAug 7, 2024 · A confidence interval is the mean of your estimate plus and minus the variation in that estimate. This is the range of values you expect your estimate to fall between if you redo your test, within a certain level of confidence. Confidence, in statistics, is another way to describe probability.
