Hello, STATA experts!



I need your help. Right now I'm in the process of writing my research paper, however, I'm stuck with the following issue.



I've conducted a survey an 'audit study' on the topic of racial discrimination on the job market. I've created 4 identical profiles (for the sake of the example let's name them A, B, C, and D) with the only difference in the names of the applicants. then I applied to a 1000 jobs with each application (so in total 4000 responses).



what I want to do is to measure if the ratio A/A (my control group, least discriminated or no discrimination at all = 1) is significantly different from A/B, A/C and A/D (or vice versa), I need this in order to understand if there is a room for discrimination. thus, if the difference between the ratios is significant that should mean there is discrimination.

I've attached the txt file with data in it. there are 4 data points for each profile (A,B,C,D)

0 - means 'rejection'
1 - means 'positive response'
2 - means 'employer seen your application, but didn't respond'
3 - means 'employer didn't see your application'



I just can't figure out how to build a model in STATA so it'll be correct to analyze and draw conclusions.



Thank you in advance!
