Week 6

In this week we are going to expand on inferential statistics by introdcuing the very general notion of statistical model formulation. In short, that is to set up an equation or function that specifies how the observed response is made up. In addition we are going to work with the analysis of variance (ANOVA) and the associated F statistics and distribution.

Hand-in assignment

Exercise 17.3 Diet and fat metabolism - ANOVA question 1 to 6 is to be handed in (through absalon or as hard-copy Friday night).

Question 7 to 11 verifies the questions, so please use those for checking your results - however, we DO NOT correct these if you include them in the assignment.

You are welcome to put in R-code in the assignment, but it is your argumentation and interpretation that are the most important.

Exercises

For Monday work through the following exercises:

For Wednesday work through the following exercises:

Important

Exercise 17.7 includes more than two factors and further interaction between those - this is not part of the curriculum, but being able to compute the numbers in an ANOVA table is.

Case III

The third case should be handed in as a slide-show with voice no later than Friday evening.
