Fieller’s Confidence Interval for Risk Ratios: Removing the Taylor Approximation

The previous post showed that the log-transform delta method CI for \(RR\) achieves its nominal 95% coverage when the expected number of positive control responses \(\mathbb{…

How Reliable Is the Delta Method CI? Bootstrap Validation and Sample Size Planning

The previous post derived a log-transform delta method CI for the risk ratio \(RR = \frac{p_1}{p_0}\):

Confidence Intervals for Brand Lift: The Delta Method on Risk Ratios

Every Brand Lift Study (BLS) is a 2×2 table: exposed vs. control, positive response vs. not. The risk ratio \(RR = \frac{p_1}{p_0}\), where \(p_1\) and \(p_0\) are the…
