I have gone from 2 equations with 2 unknowns (a and t) to 4 equations (x and y versions of each previous equation) with 3 unknowns (a.x, a.y, and t). Webb21 juni 2024 · With 8 independent equations/constraints, df = 2, and you can write everything in terms of 2 unknowns, so you have 2 independent data points. Now trying to relate this to linear regression. In Y = beta0 + beta1*X + error, I suppose that's 2 independent constraints (beta0 and beta1), so df = n-2.
