Listed 100 out of 1730 observations
Use the count() option to list more

I am new to Stata and I would really appreciate some help here. I have some observations for companies that rotated their auditor partner and their corresponding variables (auditfees, size, etc) I have included a sample which I have omitted some control variables such as ROA, Leverage etc. What I want to do is match the companies that rotated (dummy=1) and those that did not (dummy=0) by industry and size. For size I want closest match (probably the difference shouldn't be more than 0.5)

After matching I would like to produce a report showing the matched sample. Please let me know if I'm missing to include anything that might be helpful in answering the question.

Thanks a lot
