Two new Bloomberg Posts!!

April 28, 2020

Guys I’m sorry I forgot to blog last Friday about a piece I wrote:

 

Trump Is a Machine-Learning Algorithm Gone Wrong

His bizarre behavior suggests he’s running low on data.

 

Also here’s a piece that came out yesterday that I’d love to hear your thoughts about:

 

We Can’t Get Together Until Tests Get Better

More coronavirus tests won’t be enough to stop social distancing. Better tests might be.

 

 

More columns are here.

    Hi,
    I LOVE your posts but must I buy a subscription to Bloomberg to read them? Thanks in advance for an answer.

      I think you get a few free articles a month but you have to subscribe for that. Sorry.

    They have very high false negative rates, meaning that they would erroneously allow a lot of sick people to interact with everyone else, all but guaranteeing more super-spreader incidents.

    An imperfect test can still help get the reproductive rate below 1, though? Say it has 70% sensitivity but is fast and available and used to test all contacts of each case detected. Yeah, 30% of the infected contacts will be missed. Unfortunate for those people and their own contacts.

    But if a mean 2.5 transmissions could be reduced by 70%, that leaves 0.75 transmissions. For the community the big question is exponential growth or decay.

    I don’t want people to dismiss the value in test-and-trace approaches even with imperfect testing.
