Another misprint in Stock and Watson

For seminar 3:

On the TOP of page 251 in Stock and Watson (exercise 6.10c) some essential parts have dropped out when they printed the book. The complete sentence should read as follows:

Thus, if you are interested in Beta1, it is best to leave X2 out of the regression if it is correlated with X1.

Where the bolded parts are missing from the book. Hope this makes you able to prepare well for the seminars this week. Good luck.

Herman.
