  1. After all this work, let's use our model to make
  2. a prediction. We need to exponentiate the result of our
  3. model. Since we took the log of price. Let's take
  4. a look at an example from Blue Nile. We'll use
  5. the full model m5, to predict the value of the
  6. diamond. Try to understand what this code does. If you
  7. see something you don't understand, look it up in the
  8. documentation, then answer the question. Evaluate how well the model predicts
  9. the Blue Nile diamond price. Think about the fitted point estimate. As
  10. well as, the lower and upper bound of the 95% confidence interval.
