We are happy to announce a beta version of CEM is available for SPSS. Even though there are versions of CEM available for R and Stata, we wanted to make sure that anyone could use this method, regardless of software preferences. The CEM extension bundle adds a CEM command along with a dialog box in the Analyze menu. Now you will be able to run CEM to find imbalances in the data and create matched datasets that reduce model dependence, bias, and inefficiency. We have sections on this site with installation instructions, usage notes, and troubleshooting tips. If you run into any problems, please feel free to Contact us on the CEM mailing list.
