Description

The root of the Mean Squared Error between the exact value and the predicted one.

Usage

1
RMSE(Y, Ypred)

Arguments

Y

a real vector with the values of the output

Ypred

a real vector with the predicted values

Value

a real which represents the root of the mean squared error between the target response Y and the fitted one Ypred:

RMSE = sqrt(mean((Y-Ypred)^2)) .
