in #regression, noise is assumed independentβ€”but none of that matters when sample sizes are low…

here the #correlation remains approximately the same at -0.065 irrespective of noise πŸ¦–, but will range from -1 to 1 with small samples

Yeah it will β€” it also happened with the submit button and I clicked it maybe too many times as I got 4 exact emails back-to-back that it was submitted 🀷
