Knowledge Base on HIV/AIDS Care: Cooperative Agreement
 Knowledge Items That Develop Recursive Decision Trees (or Sample Partitions) Using Exhaustive CHAID (Chi-square Automatic Interaction Detector) or Related Analysis Methods

These links approximately 1000 examples of recursive partitioning trees of data collected to evaluate the service needs of individual living with HIV/AIDS and the effectiveness of innovative programs developed to meet these needs. Most of the models and analyses are by G. J. Huba, Ph.D., of The Measurement Group, conducted in 1999, 2000, and 2001. Many of the analyses on Training were designed and conducted by A. T. Panter, Ph.D. in 1999 and 2000. The methods developed here are more generally applicable to issues of data mining, especially in applications to healthcare and human services research. Click on the right side ("light blue") of the top banner to go to the start of the Knowledge Base on HIV/AIDS Care which is a general online Knowledge Base of empirical research findings from the program evaluation of 27 innovative models of HIV/AIDS care. The Measurement Group is the cross-cutting, national evaluator of this grant initiative funded by the Health Resources and Services Administration between 1994 and 1999.
