The pandemic is three months old in Minnesota at this point.  That means the model is ignoring a solid quarter, almost a third, of the data available &#8211; and, being most recent, very possibly the best data.   I hate to throw the word &#8220;useless&#8221; around willy-nilly &#8211; but if this alone doesn&#8217;t make the model useless, I&#8217;m completely bumfuzzled.  <\/p>\n\n\n\n<p> <strong>Older And Out Of The Way<\/strong> &#8211; The model don&#8217;t distinguish between populations in  hotspots like Hennepin County and the rest of the state. In Minnesota, at present,99% of the Covid deaths are concentrated in 3% of the population.   80+% of the deaths involve 1% of the state.  And yet they apply those percentages to the entire population.  This is the sort of thing that&#8217;d get sent back for rework in the private sector.<\/p>\n\n\n\n<p>And basing mortality predictions across the entire population on numbers that are so flawed at the concept level is bad math at best, dishonest at worst, and a tool used to deceive the people either way &#8211; the equivalent of a Star-Tribune poll that draws statewide conclusions based on a massive oversampling of Minneapolis DFLers.  <\/p>\n\n\n\n<p><strong>Under Bus Shoved<\/strong> &#8211; And since the overwhelming majority of deaths involve people in long term  care, the model tacitly assumes that nursing home residents will do <em>nothing whatsoever <\/em>to protect their population.  Which is possible, although there are a  whoooole lot of lawyers out there who will likely impel them to try to do a lot better than they are, sooner than later.  <\/p>\n\n\n\n<p>The model banks on long-term incompetence &#8211; natural, perhaps, for bureaucrats, but not necessarily representative of the population at large.   <\/p>\n\n\n\n<p><strong>Conclusion<\/strong> &#8211; the Walz administration is using this model to flim-flam a state that, signs show, is getting tired of being lied, condescended and talked down to. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>I watched Governor Walz&#8217;s presser last night.
