Bayes Calculator for Covid-19

[RogGuay]

I have been wrestling with my mental model of Bayesian statistics, so I created a Bayesian calculator stack for Covid-19 antibody testing. Actually I think it can be used for any thing that involves false positive and false negative results.

I would appreciate it if any of you Bayes experts would check it out for accuracy. I am only about 48.75% good at statistics!

Thanks very much,
