rtestim: Time-varying reproduction number estimation with trend filtering
Fig 9
Estimated instantaneous reproduction numbers for influenza in Baltimore, Maryland in 1918.
The left panels show estimates for a set of 50 tuning parameters. The right column displays the CV-tuned estimates with approximate 95% confidence bands. The rows (top to bottom) show using Poisson trend filtering with k = 1, 2, 3 respectively.
