I have a series of health parameters e.g. heart rate, age, blood pressure, blood glucose level of >1000 patients with heart disease. I want to determine which parameters can predict the likelihood of an individual suffering from heart disease. Once I determine the best combination of these parameters, I can use this formula to calculate how likely a person will suffer from the heart disease. May I know which method should I use? And is there any simple and free software can do the job? Thank you very much. Alan
