Summary

A novel procedure called "deep-testing" applies deep learning to classical statistical hypothesis testing, specifically for dependence detection. The method trains a deep neural network as a classification map using simulated data under both null and alternative hypotheses. This approach leverages the strong discriminating power of neural networks to construct a highly powerful statistical test. As a proof of concept, deep-testing was applied to independence testing, a fundamental problem in statistics. A large-scale simulation study demonstrated that deep-testing achieved the highest overall power among nineteen competing methods across a wide array of complex dependence structures, confirming its viability and effectiveness.

Key takeaway

For research scientists developing or applying statistical hypothesis tests, deep-testing offers a powerful alternative to traditional methods, especially for complex dependence structures. You should consider integrating deep learning classification maps into your testing frameworks, leveraging simulated data to train highly discriminative test statistics. This approach can significantly improve test power and accuracy in distinguishing between statistical models.
