Probability of an outcome given multiple attributes

  1. 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?

  3. I don't know about joint probability, but I'd say something like this would do:
    P(being obese) = P(person with BMI x being obese) * P(person with Body Fat Percentage n being obese)
