rmse {envalysis}

Root mean square error

Description

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?
