The R code from section yesterday is here.

A writeup on the two ways of characterizing the exponential GLM is here.

Note that we run into a similar issue with the exponential GLM as we do with the gamma GLM; there's a stray negative sign floating around that can make life difficult unless you keep track of what the different parts really mean.

There will be no section this week for PSTAT 220B.  Next week will cover the exponential family and moment generating functions.

For those of you who have taken 207, note that the form we use for the exponential family in this class is significantly different from the form used in the 207 sequence.  You can convert one to the other, but it's not always obvious how to do so.
