optimization: optimization() function

In Yannuo10/bis557: Homework 1

Description

one way to select the best lambda forridgr regressions.

Usage

optimization(
  form,
  dataset,
  contrasts = NULL,
  lambdas = seq(-2, 2, 0.01),
  nfold = 10
)

Arguments

form	a formula;
dataset	a data frame used for the function;
contrasts	a list of contrasts for factor variables
lambdas	a sequence for selection
nfold	number of folds to be used

Examples

library(rsample)
library(rsample)
library(purrr)
library(foreach)
library(Matrix)
library(glmnet)
library(tibble)
library(doParallel)
registerDoParallel(cores=2)
library(MASS)
data(iris)
fit_linear_model <- optimization(Sepal.Length ~ ., iris, contrasts = list(Species = "contr.sum"), lambda = seq(0, 2, 0.01))
