Dumb conceptual question: Do the parallelogram and extension of exposures method result in the same outcome when bringing premium to the current rate level?

No. The parallelogram method is a rough approximation while the extension of exposures is precise. The extension of exposures method re-rates each historic exposure using the current rating algorithm and factors while the parallelogram method adjusts each by the average change for the group (year).

For the TIA:
In the solution for exercise 1 on c.4.8 - likelihood test.. why is l(3) used when we should have used l(50)?

Should the prob go on to say the log likelihood at 50 is -619

I'm finding 86-180 to be the toughest of the SOA..like much much harder than all the first bunch and last bunch. Anyone else agree/disagree??

Finally got to that 7 EL (6.98, but I'll take it). Feel like I've ironed out everything I was shakey on. Time to grind these next 5 days. Good luck in your last minute prep everybody!

How is the formula sheet displayed on the computer? Is it literally just an electronic version of the print-out? (Though I'm assuming we'll have a separate calculator for normal distribution.)

It is almost just an electronic version of the print out, except it is divided into 5 sections (a cover page that tells you to round when using the normal table as well as gives you the standard normal density, continuous distributions, discrete distributions, chi-square table, normal table). Unless they changed it from C, it's an image file that can't be searched.

No normal calculator, you have to look things up on the table.

Cool, thanks!
