Multiple regression is completely inappropriate here given the nature of the response. You might get somewhere with logit regression but even fitting a model with 5 predictors could be a tough call when you have only 29 positive responses. You write as if you have tried multiple regression already, but consider that it will predict values out of range much of the time. | |
