Note that there was an error in the R code for Chapter 7, in the file r-code-week6.r where the training error error.train.all was computed on line 150 in the code. It should have been computed as the mean of the squared residuals and not the sum. This is now corrected in the available file. Since you were supposed to use that code as a source of inspiration in the first mandatory assignment, many of you have probably copied this error. I appologise for this! This will of course not affect whether you pass the assignment or not.

Note that it is allowed to cooperate on the mandatory assignment, but you should all hand in a separate answer. You may of course ask questions about the assignment during the weekly exercise hours on Mondays. Further, many of the problems require programming. You do not have to use R, but if you use another programming language, we might not be able to help you. Also note that there is a lot of relevant R examples in the R code posted in the time table for January 28, February 4 and February 19.
Good luck!

Due to an intensive course, that uses our room, there is no teaching next week, and therefore no weekly exercises either. I encourage you yo use the time to catch up with the material covered so far (Ch. 2, first half og Ch. 3 and ch. 7), as well as the weekly exercises given so far.
