As for @GretaGarbo recommendation, make sure you check the linearity of the logit assumption in logistic regression.

Hello,

Thanks a lot for your help. The logistic regression works well! @Dason, I used excel with "RegressIt" free add-in.

Glad to hear you had 'success'! This will generate predicted probabilities, which can be used to interpolate values of your continuous variable within the range included the sample.
