OCEE Code

This page provides access to the S-Plus code, with C libraries, to execute the Optimal Combinations of Estimating Equations analysis, as described in the paper "Optimal Combination of Estimating Equations in the Analysis of Multilevel Nested Correlated Data" by Julie A. Stoner, Brian G. Leroux, and Matthew Puumala, published in Statistics in Medicine (2008).

An additional reference is Stoner, J.A. and Leroux, B.G. (2002) “Analysis of Clustered Data, A Combined Estimating Equations Approach”. Biometrika. 89(3):567-578..
