The Univ. of Washington website projects 66k mortality for the UK. I sure hope that's wildly inaccurate (as previously posted this a.m.). On a hopeful note, yesterday's actual mortality came in at 786, about 550 less than projected. Hopefully that trend will continue, prompting revisions that prove much more accurate. So one point of statistical awareness for folks is around statistical uncertainty. That predicted figure of say, 1200 likely came with a LOT of uncertainty. That's because predictive modelling is hard and can't account for everything. In statistical terms, that would have been reported as 1200 +/- 500 (purely back of envelope here). This means that the model is predicating mortality at 1200, but the actual value may range from as low as 700 to as high as 1700. Stealing an example from earlier, you can see: Prediction was 421, but the range was 297 to 593, so a +/- of 172. In short, don't get excited unless the values is outside that confidence interval. Then what's the error on the Univ. of Washington predictions, and what is it compared to the true reported value?
