Dear all,

The problem is the following: I have panel data on the spread of covid-19 and would like to compare spillover effects between two groups. So i.e. how do units in group 1 affect one another vs. how do they affect units in group 2.

I am following a paper by LeSage and Chih in that for this I need to separate all the individual spillover effects (i.e. unit x to unit y etc) into different groups and then compare those groups. These should be listed in a matrix that contains all the direct and indirect effects - a matrix of partial derivatives. What I do not quite understand is where stata stores these matrices after running the regression and how I can work with it?

Any spatial regression command will do HETSAR, XSMLE etc

Any help will be greatly appreciated
Thank you!
