Fitting a linear regression model
The parsnip
package provides a unified syntax for the model fitting process in R.
With parsnip
, it is easy to define models using the various packages, or engines, that exist in the R ecosystem.
In this exercise, you will define a parsnip
linear regression object and train your model to predict selling_price
using home_age
and sqft_living
as predictor variables from the home_sales
data.
The home_training
and home_test
tibbles that you created in the previous lesson have been loaded into this session.
