As written, this is a strange question! You imply that you do not have data on the response (0/1) variable at all, only on the explanatory variables. In that case there is no possible estimate, because that would require data on at least some of the values of the response variable. I think you should explain more clearly and explicitly what the information is that you have for all the variables.
