Relative Squared Error (RSE)
Description
It estimates the RSE for a continuous predicted-observer dataset.
Usage
RSE(data = NULL, obs, pred, tidy = FALSE, na.rm = TRUE)
Arguments
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. |
Details
The RSE is the ratio between the residual sum of squares (RSS, error of predictions with respect to observations) and the total sum of squares (TSS, error of observations with respect to its mean). RSE is dimensionless, so it can be used to compared models with different units. For the formula and more details, see online-documentation
Value
an object of class numeric within a list (if tidy = FALSE) or within a
data frame (if tidy = TRUE).
Examples
set.seed(1)
X <- rnorm(n = 100, mean = 0, sd = 10)
Y <- X + rnorm(n=100, mean = 0, sd = 3)
RSE(obs = X, pred = Y)
