Webdata-driven confidence intervals that may be biased, with empirical coverage well below their nominal target. 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 us- WebThe goal should be to collect a minimum of 120 data points for each partition, which is necessary for determining the 90% confidence interval around an RI ( 2 ).

A robust confidence interval is a robust modification of confidence intervals, meaning that one modifies the non-robust calculations of the confidence interval so that they are not badly affected by outlying or aberrant observations in a data-set. Example In the process of weighing 1000 objects, under practical … See more In statistics, robust measures of scale are methods that quantify the statistical dispersion in a sample of numerical data while resisting outliers. The most common such robust statistics are the interquartile range (IQR) … See more These robust estimators typically have inferior statistical efficiency compared to conventional estimators for data drawn from a distribution without outliers (such as a normal … See more Like Sn and Qn, the biweight midvariance aims to be robust without sacrificing too much efficiency.
