Previous: Bayes Theorem
- Two hypothesis: the patient has cancer,
, the patient doesn't have cancer, 
- Prior knowledge: over the entire population of people .008 have cancer
- The lab test returns a correct positive result in 98% of the
cases in which cancer is actually present and a correct negative in
97% of the cases in which cancer is actually not present
-
- So given a new patient with a positive lab test, should we
diagnose the patient as having cancer or not??
- Which is the MAP hypothesis?
- Has cancer -
- Doesn't have cancer -
-
- exact posterior probabilities -
