Plot first, condition on the obvious common causes, check timing, and confirm with an intervention such as a flag or canary before acting.","language":"en","type":"article","tags":["incident-response","methods","observability","statistics"],"sources":[{"title":"SciPy documentation: scipy.stats.pearsonr","url":"https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.pearsonr.html","attribution":"","license":""},{"title":"SciPy documentation: scipy.stats.spearmanr","url":"https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.spearmanr.html","attribution":"","license":""},{"title":"Greenland et al.
