Interesting idea -- I have a few questions about how this would work: 
1.  What's your dependent variable? If it's a dichotomous outcome (acceptance/rejection), you'd need something more sophisticated than run-of-the-mill regression -- particularly if you're interested in calculating predicted probabilities.
2. How do you operationalize your independent variables? This would be particularly consequential in the case of things such as "fit" or "research experience," which an applicant may be unable to judge objectively.
3. There are likely many latent (i.e. unobserved) confounders that influence a given school's admissions decisions; for example, subfield quotas, applicants' adherence to the dominant theoretical orientations within a subfield, faculty availability, etc. How would your model account for these factors?
Again, very interesting idea -- however, you should be sure that your model is accurate before soliciting others' information online. 

Several people on this thread have expressed suicidal thoughts. If you are having these thoughts, it is important that you seek professional psychological attention. If you feel that you are in a state of extreme emotional distress or may be a danger to yourself or others, consider contacting loved ones and/or the National Suicide Prevention Lifeline (1-800-273-8255). Developing resilience in the face of rejection or other difficult circumstances will be critical to our lives and our professional success, regardless of whether we ultimately pursue a PhD or not. That starts with developing healthy coping strategies. Please seek help from professionals who can help you to develop those strategies. Mental health comes first. Finally, please know that you are not alone. You are not a failure. Your life is not hopeless, and it is not meaningless.
