WebMay 10, 2024 · Normalized RMSE = RMSE / (max value – min value) This produces a value between 0 and 1, where values closer to 0 represent better fitting models. For example, suppose our RMSE value is $500 and our range of values is between $70,000 and $300,000. We would calculate the normalized RMSE value as: Normalized RMSE = …

Webthen the R 2 can be negative. This is because, without the benefit of an intercept, the regression could do worse than the sample mean in terms of tracking the dependent variable (i.e., the numerator could be greater than the denominator).
