This function computes the root mean square error (RMSE) between a vector of
observed values x and simulated values y. rel = FALSE
returns the absolute RMSE, rel = TRUE the relative one. If
na.rm is TRUE, missing values are omitted before the
computation proceeds.
Usage
rmse(x, y, rel = F, na.rm = T)
Arguments
- x
a numeric vector containing observed values.
- y
a numeric vector containing simulated values.
- rel
logical. If TRUE, the relative RMSE is calculated, if
FALSE the absolute RMSE is returned.
- na.rm
logical. Should missing values be removed?
