Web1 Feb 2024 · Accepted Answer. As dpb said, it is impossible to know if some arbitrary value for RMSE is good or bad. Only you know if it is good, because only you can know how much noise you would expect in the data. The point is, when you use a model on some data that generates an RMSE, there are TWO components to the error, noise and lack of fit. Web$\begingroup$ In RMSE we consider the root of number of items (n). That is root of MSE divided by root of n. Root of MSE is ok, but rather than dividing by n it is divided by root of n to receive RMSE. I am feeling that it would be a policy. Reality would be (Root of MSE)/n. In that way MAE is better. $\endgroup$ –

WebThe first goal of root cause analysis is to discover the root cause of a problem or event. The second goal is to fully understand how to fix, compensate, or learn from any underlying issues within the root cause. The third goal is to apply what we learn from this analysis to systematically prevent future issues or to repeat successes.
