There are several powerful statistical analysis software, such as Stata, SAS, and a host of other packages with different levels of elegance, completeness, and support. Preferred is Stata because of its extensive contributions from its users and reliable technical support. I will add Stata commands to perform all the examples of the book. The commands are simple and quick to run. I will provide an appendix with the list of the commands used in the manuscript, their syntax, and a brief description of the output they create.
