Linear Regression Challenges

Challenge 1

We are fitting and checking the predictions on the exact same dataset! Divide your data into two sets: a training and a test set (roughly 75% training, 25% test). Fit a model on the training set, check the predictions (by plotting predicted values versus actual values) in the test set.

Challenge 2

Build a model that also uses average director gross as a feature (one of the predictor variables). Fit and evaluate. Would you use this model to predict gross revenues of upcoming movies?
