Coronavirus COVID-19 USA Peak Caseload Prediction with daily tracking updates

Each day I will update the known cases, and if warranted update the transmission rate (which would reflect lockdown effectiveness).  The model will update to show revised date and magnitude of peak caseload, and risk of encountering an infected person if venturing out.

Highlights for 3/27 are
COVID-19 flattening effectiveness and lockdown removal scenarios

A near-optimal strategy (based on prediction with actual data through 3/27) is to release lockdown for one week on June 8, followed by one more week of lockdown, then permanent unlock.  If you think you can do better, download the spreadsheet and go for it!

This model now automatically adjusts transmission rate based on previous days new cases and herd immunity (percentage of population that already had it).  It does not predict policy variations, but assumes continuation of current day's policy.  With variation in future lockdown, there should be follow on peaks which will not be predicted here.  If flattening is partitioned (by state and city, for example) and more successful in some places than others, you would get a separate series of ever lower peaks like below, which do not indicate new outbreaks, but later peaking partitions:

One can get doublel humps out of the model by reverting to the initial transmission rate less herd immunity to simulate removal of lockdowns and social distancing.  I will lmake some revisions and plot a few cases tomorrow.
