Why 10th day? Why not do an appropriate series analysis from day 1 comparing any countries under consideration? Why trust a 3rd party source that arbitrarily used 10th day in order to game the stats? Why not just use source data and look for yourself? Is it because the trend lines wouldn't be as alarming?

US net of plague ship USS NY (35% of total gross US of 2,038). Actuals through 3/28, 3/29-4/5 projected based on event-to-date ratio with Italy.

Why 10th day?.

The graph starts on the 10th death not the 10th day.

The problem is you don't know when day 1 was. Picking the 10th day, approximately the 1000th case starts with a statistically significant number of cases, normalizing the time 0 for staring the exponential growth.

thanks for this, but something else is that I don’t trust New York’s numbers. I do extremely large data set analytics in the exabyte range and I would easily toss New York’s numbers because they are so far outside all ranges as to be suspect and untrustworthy.
