    Excellent question.

    Here’s a video explanation.

    There are two components that you need to take into consideration: the range of the response distribution and the range of the mean. Once the SOA’s modules are released in a few weeks, you will be able to review the chapters that cover this. By going through several examples of past exams, you can see why they justify each choice.  Almost every sitting of PA has included a GLM question. You also need to consider the interpretation – does it need to be easy to understand? What’s the canonical link function?

    If you enroll now you can get access to more than 28 hours of video tutorials. You can practice on realistic exams and then get feedback in real time. There are a number of lessons that cover these topics and in addition to the SOA’s answers, we also provide alternative answers.  There are often multiple correct ways of answering these questions as long as you can justify your reasons, which our examples cover.

    Good question, Porkins.

    In all previous sittings, the Prometric staff have provided candidates with a printed project statement and so you can plan to use a pencil to underline sections or take notes.  There’s no algebra required so scratch paper is not needed.  Excel can be used as a calculator.  You can gain an advantage by building up your typing speed to 70 words per minute so that you’ll be able to write 20+ pages in your report.  Many people run out time before being able to write everything that they plan to.

    Pivot tables are disabled on Prometric computers.

    A lot of people get stumped on the ggplot formatting when first starting out.  Fortunately, the SOA gives you template code to create all of the graphs that are needed.  You can use Excel for inspecting the data, but just not with a pivot table.  In R, just use write.csv(data, “data.csv”) to create a copy and then open it in Excel.

    You can find save yourself time by only learning the R necessary for this exam.  In Chapter 5 of our Spring 2021 Study Guide, there is an explanation.

    Hi Angelo,
