Hi, thanks for your amazing solutions.
I found that in problem 6.10, you didn't include the intercept when calculating pred by omitting the coefficient of intercept. Though the outputs are almost same, R^2 can be very different.
Reference:
When is it ok to remove the intercept in a linear regression model?
