Abstract:
|
This study considers several alternative estimators of Odds Ratio (OR). The estimators considered are the sample OR, Mantel-Haenszel estimator (MHE) and the preliminary test estimator (PTE). The properties of the estimators are studied with respect to bias and mean squared error. It is revealed that the PTE is biased. However, with respect to the mean squared error property, under certain conditions this estimator is more efficient than the other two estimators.
