[2026 update] Correlation in a self-tracked dataset: what it can support

GT
g.tanakaTL3Regular30 Apr 2026#1

Posting this under the heading it deserves: Correlation in a self-tracked dataset: what it can support Everything below is what sits behind that.

Posting a small dataset on Correlation. It is mine, it is uncontrolled, and the method is stated so it can be discounted appropriately.

What I would like is not agreement but a second dataset collected by someone with no stake in mine. If one exists I would rather read it than argue for this one.

Checked the Correlation claim against the primary source this morning. It survives, with a narrower scope than the version quoted here. Posting the narrower scope.

Taking the opening post at face value and following it one step further.

Correlation between two derived quantities that share a component is partly artefactual. It is a common trap in analyses of ratios.
