Dear all,

I am currently conducting a fixed effects panel regression in Stata with the following variables:
CompanyID
Group (either 1 or 0)
Year (2005-2015)
Performance (profit in €)

The one group of companies went through a training (group 1) the other group of companies that is comparable in terms of their business model etc. did not attend the training (group 0)
The main question is what impact the training has on the dependent variables (among others profit).

In addition I want to include a mediator into the model: For instance I want to check if the company's leadership motivation is effected by the training and has an influence on the DVs (e.g. profit)
Do you know how to implement this into stata? Is it possible for me to run separate regressions? e.g. one regression xtreg leadership motivation Group, fe and then xtreg Profit leadership motivation, fe?
