Randomization Inference for Matched Pairs with Binary Outcomes

Scheffe's Method for Multiple Comparisons

I’ve written previously about using the Bonferroni correction for the multiple comparisons problem. While it is without a doubt the simplest way to correct for multiple comparisons, it is not the only way. In this post, I discuss Scheffé’s method for constructing simultaneous confidence intervals on arbitrarily many functions of the model parameters.

Contingency Tables Part IV: The Score Test

The score test can be used to calculate p-values and confidence intervals for A/B tests. The score test considers the slope of the likelihood function at the parameter value associated with the null hypothesis.

Optimal Experiment Design

We can plan sample sizes to control the width of confidence intervals.

Confidence Intervals

Statistical analysis is not complete without an estimate of residual uncertainty.
