https://communities.sas.com/t5/Statistical-Procedures/Logistic-or-Probit-regression-Which-is-better/m-p/18988#M544 My model has one dependent variable with 3 independent variables, which looks like:<BR /> <BR /> a=b+c+1/d<BR /> <BR /> Both dependent and all independent variables (a, b, c, d) are BINARY. In this case, what kind regression do I have to use? Logistic or Probit or anything else? <BR /> In what condition do I have to use Logistic, and in what condition do I have to use Probit in my model? Can you give me good references, if you know any? <BR /> <BR /> A Regression Newbie...<BR /> Onugi97 Mon, 10 May 2010 20:22:29 GMT onugi97 2010-05-10T20:22:29Z https://communities.sas.com/t5/Statistical-Procedures/Logistic-or-Probit-regression-Which-is-better/m-p/18988#M544 My model has one dependent variable with 3 independent variables, which looks like:<BR /> <BR /> a=b+c+1/d<BR /> <BR /> Both dependent and all independent variables (a, b, c, d) are BINARY.

Maybe you need to say more about what you are trying to do.
