fitVirusCV19v3 (COVID-19 SIR Model)

Estimation of coronavirus COVID-19 epidemic evaluation by the SIR model, Code receives and plots most recent data from HDX.

This code will retrieve recent data from the HDX and attempt to fit it to a SIR model using structure created by Milan Batista (https://www.mathworks.com/matlabcentral/fileexchange/74658-fitviruscovid19?s_tid=prof_contriblnk). The model is data-driven, so its forecast is as good as data are. Also, it is assumed that the model is a reasonable description of the one-stage epidemic.

Results are saved in structure res (see function fiVirusCV19 header). Optionally the results may be printed by:

fitVirusCV19v3(“Italy",'prn','on')

The plot may be enabled or disabled via (default is on):
fitVirusCV19v3(“Italy",'plt','off')

To plot the growth rate on the figure use (def value is 2)
fitVirusCV19v3("Italy",'nsp',3)

To plot the R0 as a function of time
fitVirusCV19v3("Italy",'r0analysis','on')
