Today’s Link In something that will gladden the heart of any actuary or statistician reading this, a number of Victorian testing centres have decided to test every 5th person who comes in, whether or not they meet the testing criteria. Why does that matter? Because it will give them aContinue Reading
Marta asked whether I would be writing on the weekend. The answer (as you can see) is yes, but I’ve decided to give myself the weekend off from analysis. So only three sections today. Today’s links If you’re riding bike around, you should leave more than 2 metres between youContinue Reading
Today’s insight NSW Health has released a whole lot of new information on its website about all the cases in New South Wales. There is far more information than last time I looked. The sobering statistic is that there are now 19 people in intensive care in NSW with Covid19,Continue Reading

Since then, I’ve been reading obsessively and contributed a bit in the background to some of the Actuaries Institute material, and we now have more than 1,000 cases in Australia (there were 15 when I wrote the original blog post). This post is the start of my series of posts on the Coronavirus from an actuarial perspective.Continue Reading
