1
Expectation of the outcome using the predicted prevalence.
2
Unexplained disparity is (observed prevalence or expectation of outcome (White) –predicted prevalence or expectation of outcome using predicted prevalence (Black)).
3
Percent disparity explained is (1– unexplained disparity) /(observed prevalence or expectation of outcome(White) – predicted prevalence or expectation of outcome using predicted prevalence (Black))*100.
