# Probability of an outcome given multiple attributes

Hi,

Lets say I have the following attributes...
Body fat percentage, Body mass index
Outcome = obese (yes / no)
I have data for all attributes and outcomes. What I'd like to do is a joint probability. For example I'd like to know what the probability is of someone being obese given their BMI and body fat percentage.

I can calculate the correlation between the attributes and the outcomes. My intuition tells me that I need to combine the correlation in some way, but can't seem to find any information on this.

Can someone point me in the right direction?

You should look into regression analysis with a limited (binary) dependent variable, "limdep."

See "logit" and "probit" under: http://en.wikipedia.org/wiki/Limited_dependent_variable
