Raw data since: 2020-01-22, predicting since 2020-01-22, last sample:2020-07-13 07:30:22 n=13041698
The error reported in the figure (Err=...) is the rms error of a predictive model on the training
data for the model. The training data are the known daily (Worldometer) counts of
corona-virus cases, fat purple curve, since 22/1/2020.
At the end of each day, the best model is selected for making a prediction for the next day.
The actual count is determined at the next day from Worldometer corona virus report.
No other data points are collected from reporting sites during the day, when computing the prediction.
