Where is the proof that these suicides are the responsibility of the program?
There is none.
All you can do is run a study to compare the # of suicides committed by program grads to the # of suicides in a control group. (probably several control groups)
Then attempt to determine what exactly is the nature of the causal relationship, if there is one. (that will be determined by the significance of the disparity) The cause may be the program, it could also be some other criteria that the experimental group has in common, which the control group does not. There may not be any way to even develop a causal hypothesis, and all people will have are the numbers and percentages. Sometimes, that data alone is enough.
Due to the fact that no study has been conducted, neither you nor anyone else, can refute or confirm any sort of hypothesis regarding this. So as far as Im concerned, all of you should just STFU. You don't exactly sound like a statistician, and neither is anyone else here, so nobody is qualified to have any conclusive proof about any of this, whether the rates be that of "success" (which is a bogus, subjective criteria) or suicide. (which is slightly more concrete)
Of course, this issue has been discussed extensively in other threads already, so you either have not read them, or you are just looking to be the proverbial itchy asshole.
Also, re: OP, saying someone had the choice to kill themselves is rather redundant. If it wasn't their choice, then it wouldn't be a suicide, it would be murder.
Also, please fix your spambot. You're leaving a trail all over the place.
