In tscv: Functions and Utilities for Tidy Time Series Forecasting and Time Series Cross-Validation

Calculate the root mean squared error

Description

Calculate the root mean squared error of a numeric vector.

Usage

rmse_vec(truth, estimate, na_rm = TRUE)

Arguments

truth	Numeric vector containing the actual values.
estimate	Numeric vector containing the forecasts.
na_rm	Logical value. If TRUE, missing values are removed.

Details

rmse_vec() computes the square root of the mean squared forecast error. The metric is reported in the same units as the original data.

Value

A numeric value.
