Calculate the r_squared

Description

Usage

calc_r_squared(true_values, estimated_values)

Arguments

estimated_values	the estimated values

Value

the mean squared error from the identity line

Examples

true_values_degrees <- seq(1, 360)
estimated_values_degrees <- true_values_degrees + stats::runif(n = 360)
r_squared_degrees <- calc_r_squared(
  true_values = true_values_degrees,
  estimated_values = estimated_values_degrees
)
r_squared_degrees

# Convert degrees to radians
true_values_radians <- 2.0 * pi * true_values_degrees / 360
estimated_values_radians <- 2.0 * pi * estimated_values_degrees / 360
r_squared_radians <- calc_r_squared(
  true_values = true_values_radians,
  estimated_values = estimated_values_radians
)
r_squared_radians

# mse_degrees and mse_radians are the same, due to their normalized scales
