Dear Statalist member,

Good day everyone. I am using Stata 14.1. Here is the sample of my data. I am regressing sustainability reporting score (the y) as a function of stakeholder characteristics. Stakeholder have three characteristics; pcomm, lcomm, ucomm. Comm is stand for one of the stakeholder groups in my study. I have eight stakeholder groups and I run regression model separately for each of them.

According to theory, the y is also associated with cumulative stakeholder characteristics. Meaning to say that the theory propose that having more than one characteristics can have an effect on y. At first I run the following command,
Code:
xtreg y pcomm lcomm ucomm c.pcomm#c.lcomm#c.ucomm, fe vce (robust)
end
But, I could not find the way to interpret the result. Instead, I find many discussion refering to three factorial effects. Something like this command.
Code:
xtreg y pcomm##lcomm##ucomm, fe vce (robust)
end
Now, I am confuse which of the two is the right command that should be use to answer the theory.

I also not sure whether the interaction variable should be a factor variable or continous variable. Thanks you for your time.
