Root Mean Squared Error
The square root of mean squared error, providing an error metric in the same units as the target variable for easier interpretation.
In plain language
Same idea as MSE but takes the square root so the error is in the same units as the prediction. If predicting prices in dollars, RMSE gives you the error in dollars, much easier to interpret.
Why this matters
RMSE is relevant to implementation because it provides an interpretable performance metric that can be communicated to non-technical stakeholders. When setting acceptance thresholds for regression models, RMSE allows you to specify tolerance in business units.
Relevance
ImplementationRMSE is useful for setting and communicating model performance thresholds in business-relevant units, supporting decisions about whether a model is fit for purpose.
