Biography

Donald Hedeker’s main area of expertise is in the development and use of 

advanced statistical methods for clustered and longitudinal data, with particular 

emphasis on mixed-effects models. He is the primary author of four freeware 

computer programs for mixed-effects analysis: MIXREG for normal-theory 

models, MIXOR for dichotomous and ordinal outcomes, MIXNO for nominal 

outcomes, and MIXPREG for counts.

In 2000, Hedeker was named a fellow of the American Statistical Association, 

the highest honor in his field. He was also recognized as a University Scholar by 

the University of Illinois that same year. He serves as an associate editor for 

Statistics in Medicine and the Journal of Statistical Software. He has been the 

principal investigator (PI), co-PI, or co-investigator on many research grants 

funded by the National Institutes of Health (NIH) and the Centers for Disease 

Control and Prevention.
