SUMMARY
The discussion clarifies the distinction between Root Mean Square Error (RMSE) and standard deviation. RMSE serves as an estimator derived from model results, particularly in regression analysis, while standard deviation represents a population parameter. The two metrics are related, but RMSE is specifically used for assessing model accuracy, whereas standard deviation pertains to the theoretical distribution of data. An unbiased RMSE can equal the standard error under certain conditions.
