Odds Ratio Estimation for Small Proportion in Binomial Distribution
Keywords:
Odds Ratio, Empirical Bayes, Modified Maximum Likelihood EstimatorAbstract
In this study, we introduce the new estimator of odds ratio using Empirical Bayes (EB) for small proportions of success in a 2x2 table. The proposed estimate of odds ratio based on EB is then compared to conventional method, modified maximum likelihood estimator (MMLE), using the Estimated Relative Error (ERE) as a criterion of comparison. The result indicated that the EB estimator is more efficient than MMLE.
