WebNov 12, 2024 · TSS = RSS + ESS only applies when the sum of the residuals (not the sum of the squared residuals, mind) is 0 (or equivalently, when the residuals have mean 0). In your example, all residuals are positive, and therefore their sum is also positive, and not 0, so the equality does not hold here.
