Root Mean Square Error

Description

Calculate Root-Mean-Square Error (Deviation)

For the ith sample, Squared Error is calculated as SE = (prediction - actual)^2. RMSE is then sqrt(mean(squared errors)).

Usage

rmse(preds = NULL, actuals = NULL, weights = 1, na.rm = FALSE)

Arguments

preds

A vector of prediction values in [0, 1]

actuals

A vector of actuals values in 0, 1, or FALSE, TRUE

weights

Optional vectors of weights

na.rm

Should (prediction, actual) pairs with at least one NA value be ignored?
