Great work Hernan ! I was considering doing the same a few days ago. Let's try to work together in the same direction. We are missing tools in PolyMath, Roassal, Dataframe and Kendrick in order to build more elaborate analysis/visualizations of COVID-19 outbreak. For example, we are missing curve fitting methods (except the basic linear regression): https://en.wikipedia.org/wiki/Curve_fitting like optimization algorithm like the Nelder-Mead method: https://en.wikipedia.org/wiki/Nelder%E2%80%93Mead_method I start a board here for todos: https://github.com/orgs/PolyMathOrg/projects/1 People who are interested to help, can join the #polymath channel on Discord to coordinate.

Hello,

I have set up a new Pharo project for the analysis of COVID-19 outbreak:

Thanks to the ObjectProfile for Roassal and PolyMath contributors for the DataFrame package.

Cheers,

Hernán
