Document Summary
Lecture #9: coefficient of determination and multiple regression. As we saw, we can make a prediction, and then find a point with the same value for x but it"s value for y is not like our prediction. Thus, there is almost always a difference between the observed and the predicted: i. e. error. We already saw this when we looked at the pre! We can calculate the errors associated with both the use of predicted y and use of the mean of y by extending the sum of squares method we already used. As we saw, we can make a prediction, and then find a point with the same value for x but it"s value for y is not like our. We can calculate the errors associated with both the use of predicted y and use of the mean of y by extending the sum. We will need to make another table to solve for these values.
