RMSE

Root Mean Squared Error

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

RMSE(Y, Ypred)

`Y`	a real vector with the values of the output
`Ypred`	a real vector with the predicted values

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)) .

X    <- seq(-1,1,0.1)
Y    <- 3*X + rnorm(length(X),0,0.5)
Ypred <- 3*X
print(RMSE(Y,Ypred))
