Improvement factors with rmse
Witryna17 kwi 2013 · First of all, as the earlier commenter R. Astur explains, there is no such thing as a good RMSE, because it is scale-dependent, i.e. dependent on your dependent variable. Hence one can not claim a universal number as a good RMSE. Even if you go for scale-free measures of fit such as MAPE or MASE, you still can not claim a … Witryna3 sie 2024 · r2 = 1 - MSE (x,y) / VAR (y) If MSE -> 0, consequently RMSE -> 0, and r2 -> 1. But if RMSE -> +inf, MSE -> +inf and if MSE <= VAR (y) this will lead to r2 values lower Than 1 e.g. 0.2, 0.3, etc. So your results might place your analysis on the right track.

This shows that the model is able to generally predict the correct direction rather accurately due to the constant seasonality.
WitrynaIt is defined as the product of RMS current and RMS voltage, which we have in the second and third rows of the table: PA = 0.1307 A x 246.9 V ≈ 32.27 W. So the power factor is: pf ≈ 19.32 W / 32.27 W ≈ 0.60. Power factors are always in the range 0 to 1, with 0 indicating a purely inductive or capacitive load and 1 a purely resistive one ...
