I have to do research to find out whether there is positive relationship the female presence of audit committee and audit fees based on 5 listed firms in 2014 to 2019.

I have find data and find the descriptive data, correlation matrix analysis, and regression analysis.

Firstly, For my dependent variable is Audit fees but I am not sure about the terms and also I have no idea whether should I included network firms.

Should I Include network firms?

Audit fees = audit and assurance fee? or just audit service fees?

Is there way to find audit fees through Morningstar database?

Secondly, I have type the natural logarithm of audit fees in excel so should I type =log(audit fees)?
