ridge: ridge() function
In Yannuo10/bis557: Homework 1

another way to build a linear model. ridge regression for ordinary least squares

1	ridge(form, df, contrasts = NULL, lambda = 0)

`form`	a formula;
`df`	a data frame used for the function;
`contrasts`	a list of contrasts for factor variables
`lambda`	a constant for penalty

1 2	data(iris) fit_linear_model <- ridge(Sepal.Length ~ ., iris, contrasts = list(Species = "contr.sum"), lambda = 0.1)
