Sequential test for ratio of two means

When comparing means of two non-negative random variables, we are often interested in the ratio of two means since the ratio does not depend on the scale of underlying distributions.

From Sequential Tests to Change Detections

If we know when a potential change might possibly happen in a stochastic process then we can set a sequential test to continuously monitor whether we can tell the change

Advantages of Sequential Hypothesis Testing: 2. Flexibility and Safety

In this follow-up post, we explain another advantage of sequential hypothesis testing: Flexibility and safety. Please visit the previous post for an introduction to Wald’s

Advantages of Sequential Hypothesis Testing: 1. Sample efficiency

In this and a follow-up posts, we explain two main advantages of sequential hypothesis testing methods compared to standard tests based on fixed sample size. Sample efficiency in practice As
