The wrong exercise was given this time (the topic in exam 2010, ex 2 has not been discussed in the course). I will therefore instead discuss exercises 32 and 33.

I see that I had put the deadline on Thuesday 22. april. This is of course wrong. The deadline will be Wednesdag 22. May at 14.00.

The code for handling missing values in ex 1a) was not correct. Here is an alternative code (which also is included in an updated version of the project file)

fit = lm(logPM10~A+UTMX+UTMY+WS+TEMP+HMIX+PREC+EMI,data=d)
res = rep(NA,nrow(d))
res[!is.na(d$logPM10)] = resid(fit)
acf(res[d$Station==1],na.action=na.pass)
 

Note: If you already have done it with the commands given, you will not be punished for this.

Some small errors are corrected in the exercises for next week.

The project will be published 22 april and will have a deadline on Wednesday 22 may

Some small errors are corrected in exercises 20c and 21c

There will be no teaching this day, but the students are encouraged to meet at 10.15 anyway in order to sit and work together with the exercises. Please send me an email in case you plan to come, so I can leave a message on that there will be some students that show up.

In the Syllabus page there is a misprint file containing errors/misprints in the book. If you find others, please tell me and I will update this file

Exercise 13 c: You can assume Zi sim Poisson(exp(Yi)) here

The exam for the PhD students will be an oral exam in the week 3-7 June. In addition, a presentation of a given paper and a project will be part of the exam. Each part needs to be passed in order for passing the course.

There was a missprint in exercise 10, (i) in that tau? should have been tau in the exponential. Note also that the stepAIC command in exercise 11 is available from the MASS library.

There was a small typo in exercise 6 (wrong sign on determinant in part (a). This has now been updated. Further, 5 (e) contained some unexplained concepts. These are now defined.

Eksam: A project paper followed by a written exam. NB: Final evaluation for PhD students is not yet finally decided. Will come shortly.

The teaching will be divided into one part going through exercises and one part being lectures. How much time we use on each of these can vary from time to time.

Copies of presentations can be found by clicking on "Time and place" under "Teaching".
