Specifically designed in the context of big data in our research lab, the new and simple strong correlation synthetic metric proposed in this article should be used, whenever you want to check if there is a real association between two variables, especially in large-scale automated data science or machine learning projects. Use this new metric now, to avoid being accused of reckless data science and even being sued for wrongful analytic practice.
This long article has the following sections:
1. Formal definition of strong correlation
2. Comparison with traditional (weak) correlation
3. Excel spreadsheet with computations and examples
4. When to use strong versus weak correlation?
5. Generalization
6. Asymptotic properties, additional research
7. About synthetic metrics and our research lab
8. Conclusions
