For example,some time back I looked up this weekly death data:<\/p>\n<p>&NewLine;<br \/>\nDate   Covid  deaths<br \/>\n4\/18 17K<br \/>\n6\/20 3<br \/>\n6\/27 1  <\/p>\n<p><a href=\"https:\/\/www.cdc.gov\/nchs\/nvss\/vsrr\/COVID19\/index.htm\" rel=\"noopener noreferrer\" target=\"_blank\">https:\/\/www.cdc.gov\/nchs\/nvss\/vsrr\/COVID19\/index.htm<\/a><\/p>\n<p> It looks like deaths are down over 90% from 17K to 3 to 1, right? But then I looked at the notes under the table and found that they report deaths as the files come in from the states and it takes up to 8 weeks for the weekly data to arrive. So, actually, this CDC webpage is useless for anything about deaths in the past 2 months. This has two bad parts: (a) they don&#8217;t collect the most basic, easy, relevant, data on covid-19 in time to be useful, and (b) they give us some other numbers that are irrelevant but will fool people who don&#8217;t read the fine print into thinking they have the real numbers. <\/p>\n<p> I really would like to hear if anyone knows what&#8217;s going on down there in Atlanta. How can data collection be so bad? Washington DC economics statistics bureaucrats look like angels by comparison, so it isn&#8217;t something about the nature of government generally.  <\/p>\n<p>  Reflecting further, I&#8217;m even more amazed by how bad the CDC is. Usually  in statistics, the basic problem  is   too small a sample. Someone looks at  4 people dying in 20 cases of cancer, and says the fatality rate is 20%, and we laugh, because he&#8217;s estimating the population mean for the 100,000 cases using the sample mean from just 20 cases, and probably the sample isn&#8217;t even random. But the CDC is far worse than that. It&#8217;s  like someone who says that 4 out of 100,000 people who get cancer die, because he&#8217;s only looked at 20 cases so far. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Does anybody know why we had such lousy CDC data collection in March and why it hasn&#8217;t improved?
