Analyzing regression output
You are interested in how well the model you've just built fits the data. To measure this, you want to calculate the median absolute difference between the true and predicted earnings. You run the following line of code:
median(abs(biopics$earnings - model_1$fitted.values), na.rm = TRUE)
What do you think will be the result?
