rmse: Root Mean Square Error

In mltools: Machine Learning Tools

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?

Examples

preds <- c(1.0, 2.0, 9.5)
actuals <- c(0.9, 2.1, 10.0)
rmse(preds, actuals)
