RSR | R Documentation |
It estimates the MSE normalized by the standard deviation of observed values following Moriasi et al. (2007).
RSR(data = NULL, obs, pred, tidy = FALSE, na.rm = TRUE)
data |
(Optional) argument to call an existing data frame containing the data. |
obs |
Vector with observed values (numeric). |
pred |
Vector with predicted values (numeric). |
tidy |
Logical operator (TRUE/FALSE) to decide the type of return. TRUE returns a data.frame, FALSE returns a list; Default : FALSE. |
na.rm |
Logic argument to remove rows with missing values (NA). Default is na.rm = TRUE. |
The RSR normalizes the Root Mean Squared Error (RMSE) using the standard deviation of observed values. It goes from an optimal value of 0 to infinity. Based on RSR, Moriasi et al. (2007) indicates performance ratings as: i) very-good (0-0.50), ii) good (0.50-0.60), iii) satisfactory (0.60-0.70), or iv) unsatisfactory (>0.70).
