For Wed 19.9: work with Exercises 6,7,3 from Nils's stk 4050 (growing) collection, in more or less that order. I will lecture from Liu's Ch 2.

I have placed "R source files" here; please check that you can access, copy, modify, and use them. Keeping "com16b" in the appropriate subdirectory of your computer and then writing the command line " source ("com16b") " inside R will execute this programme, which pertains to Exercise 1. As the course proceeds you will be expected to be able to make such programmes yourself.
