In lecture 10, we discussed the conditional expected value. As I kept emphasizing during the lecture, the conditional expected value is the optimal predictor minimizing the expected square of errors (RSS is a good example of this but not 100% equivalent). We will focus on how to calculate the conditional expectation through the course, and analyze the prediction accuracy using the conditional expectation.
