SPSS Add-Ins for Multilevel Modeling
While working on the Parsing Project, I developed three SPSS add-ins that facilitate multi-level analyses in SPSS (versions 17 and later). Although the add-ins were developed specifically for use with Parsing Project datasets, the add-ins can be used in any SPSS file that is similarly structured.
These two add-ins include macros for creating group- or grand-mean centered variables. The choice of how to center variables for multi-level analyses is critical; these add-ins do not help analysts make that choice. They simply automate the tedious process of creating centered versions of already existing variables.
Multi-Level Regression (HLM Models)
This add in simplifies the interterface for creating multi-level models in SPSS.
Note: I do not have any formal help-files for these add-ins. Analysts looking to use these add-ins are welcome to email me with any questions.
