These are two cycles of models for Hurricane Dorian taken merely 24 hours apart. Do you notice something about them?
There is zero overlap between them. There is no mathematical way that the folks running these scenarios are representing the actual range of possible outcomes.
The consequences of these mathematical failures are huge. Yesterday, reporters nationwide were telling people in Florida that one of the most catastrophic storms in the history of the State of Florida was about to make landfall. Today, they are telling them that they are in the clear and the storm might hit the Outer Banks instead. Both claims are absolute bullshit from a quantitative perspective.
Why can’t the federal government hire a single quant from Wall Street to model hurricanes?
