## Converting this so that a 2 X 2 X 2 Table An Example from ?2.3 Inference About Conditional Associations In 2 x 2 x K Tables

Columbia Union College, US has reference to this Academic Journal, Inference About Conditional Associations In 2 x 2 x K Tables Demeke Kasaw Gary Gongwer An Example from ?2.3 Death Penalties in Florida in consideration of Multiple Murders, 1976-1987 Odds Ratio = 1.45 Converting this so that a 2 X 2 X 2 Table We now have 2 Partial Tables, by race of the victim Conditional Odds Ratios:

Conditional in addition to Marginal Odds Ratios This can be generalized so that K different levels To study whether an association exists between an explanatory in addition to response variable after controlling in consideration of a possibly confounding variable Different medical centers Severity of Condition Age Different Studies of the same sort (Meta Analysis)

Using logit Models so that Test Independence We wish so that estimate the conditional probabilities If Y depends on X, then If Y in addition to X are independent CMH Test in consideration of Conditional Independence Estimation of Common Odds Ratio When the association seems stable among the partial tables, it is helpful so that combine the K odds ratios into a summary measure of conditional association.
