Apply the Version 2.0 code

[MathGIS]

Dear Prof.,
I have just learn the seirsplus package with great interest. I think the Version 2.0 code is very suitable for my research on COVID-19.
I wonder whether you can share me the Version 2.0 code for our research. Also, I'd very glad to ask you to join us to help me to finish that work. Any help or suggestions are greatly appreciated.
