Default Model Fitting Function

Fits a simple mean model that returns the mean of y_train. The predict() method returns this mean for all new observations.

Usage

default_model_func(x_train, y_train)

Arguments

x_train

Matrix or data frame of training features.

y_train

Numeric vector of training targets.

Value

A list with class "default_model" containing the mean of the training target.

Examples

default_model_func(matrix(rnorm(100), ncol = 1), rnorm(100))
#> $mean_y
#> [1] 0.1482784
#> 
#> attr(,"class")
#> [1] "default_model"
