mse: Mean Squared Error (MSE)

Description

Computes mean squared error.

Usage

mse( pred, actual, weight = 1, na.rm = FALSE )

Arguments

pred

a numerical vector of estimated values.

actual

a numerical vector of actual values.

weight

a numerical vector of weights the same length as pred.

na.rm

a logical value indicating whether NA values in pred should be stripped before the computation proceeds.

Value

The computed mean squared error (numeric value).

Examples

# NOT RUN {
pred   = c( 2.3, -1.4, 0, 3.45 )
actual = c( 2.1, -0.9, 0, 2.99 )
  
mse( pred, actual )
   
# }
