[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]None of Maryland’s numbers are increasing (positivity rate, hospitalizations, deaths), not declining as rapid,u as before, bu to de you get below 5 percent, that is inevitable.[/quote]

Maryland's new cases per day are very much increasing.

Deaths lag by about 4 weeks.  Our death rates will rise, and hospitalization rates will rise sooner.[/quote]

Are you slow about everything or just feign stupidity with respect to covid?  After four months of this, you must realize that the number of positive cases is meaningless because it is dependent on how many tests are given.  The number that is relevant is percent of tests positive.[/quote]

Please enlighten us, professor, of what a random sample would look like. 
Somebody is wrong on the internet!

Until we get to a pervasive testing regime, the percent positive absolutely is a function of the number of tests because you are sampling on the dependent variable. [/quote]

The number of positive tests is dependent on how many positives cases are in the community. If the spread rate is 10% then 10% of tests is positive no mater whether you do 50 tests a day or 500. [/quote]

This statement is true if you are sampling in a truly random fashion. You aren’t. The fewer the number of tests the more likely a test is used on someone with a high likelihood of having the disease.

If you don’t understand the implications of this, please don’t stat-splain to the rest of us. [/quote]

You are making an assumption that with few tests only symptomatic people will get tested. As we have a great availability of tests now, we are requiring testing for everyone before procedures, with possible exposure etc. We are sampling a truly random sample now. There are test sites in Maryland that do not require a doctor order and are free. We are weaning our asymptomatic carriers. [b]Maryland testing program is robust and yes, we have a random sampling[/b]. [/quote]

Testing more people, including asymptomatic people =/= a random sample[/quote]

+1 I'm a professor and teach a methods/statistics course. That is not the definition of a random sample. [/quote]

PP again, what is happening is closer to Convenience sampling.[/quote][/quote]
