Build a multiple linear regression model with all potential
predictors in the data set, provide a summary of the fitted model,
the variance inflation factor for each predictor, and show
diagnostic plots for the model. Caution: please make sure each
predictor has the correct R object type; otherwise your model may
be insensible.
Please use the data set Auto from the R
library ISLR. You will build linear models to predict the
response mpg.
