Looks like the vast majority of students at my school will not be returning this school year. Graduating students will have to return. However, I finish teaching them before the day they have to go back. Unless I’m informed otherwise, I only have to go back for the 1st and 2nd week of June to administer school-leaving exams for the graduates. Everything else I can do online.
Thanks. There was an article today about the Lazeretto house near the Philly airport. So we took a drive to check it out. it was built in 1799 and served as a quarantine house for 100 years for ship passengers coming up the Delaware. Yellow fever and typhus patients
mostly. Think today it’s township offices.
True/false positive/negative are just what they sound like. False positive is test positive but person is negative.
Short of DS dropping in to explain (and misspell) Bayes’ rule, there is a tweet with a decent explanation of the issue up thread.
It’s maybe counterintuitive, but in a nutshell - - the smaller the prevalence (of what you’re testing for) in the whole population is, the more likely positives in the tested sample are false.
Well in any case, your posts made me think about it from a different perspective rather than just assuming. And that caused me to look it up and know for sure, so that’s a good thing.
Nah, that makes perfect sense. Tiny mistakes over a large population end up with a lot of mistakes compared to the actual number of cases if it’s something rare.
You mean in the Santa Clara testing? I read that the test they used for that was 99.5% accurate IIRC, but there were concerns with the sample size that had established the testing proficiency.
The problems with the Santa Clara results go well beyond the accuracy of the test used.
Edit: Tested at 99.5%, and at least as good as 98.2%
Man, I just can’t see how these dates can kinda be true. Are they assuming that we’re all hardcore social distancing? Apparently people can be contagious for a week+ before feeling sick.
How are the LIBERATE homies doing today? Needing to feel good and seeing pictures of these people suicide themselves for Daddy is about the closest it gets these days.
My mom too - although she never liked Trump anyway but I think voted for him because of the chopping up little babies thing.
She swears she’s not voting for him this time but I have my doubts. Rs can always hammer on abortion for a few months leading up to the election and get her back in the fold.
