1. What is Panel Data Toolbox?

Panel Data Toolbox is a package that allows estimating popular and
novel panel data models in MATLAB.

2. Is it free to use Panel Data Toolbox?

Panel Data Toolbox is free to use, but if you use it please acknowledge
the hard work behind it, and cite it as reference. See “How to cite“.
