About StenStat

StenStat began as a statistical consulting company in 1983. It was founded by Herbert Stenson, Ph.D. who was then a professor at the University of Illinois at Chicago and is now emeritus. Consulting took many forms --- statistical aspects of medical research, expert testimony in court, and advising on the design of experiments, to name a few.

In 1986 Dr.Stenson began writing software for add-on modules to the popular SYSTAT statistical package. The first of these was Testat, a module for analyzing the data from psychological and academic tests and surveys. This was followed by Signal, a module for Signal Detection analysis. Then came QCStat for quality control analyses, followed by Design, a module to generate complex research designs. In addition, Dr.Stenson implemented important extensions for the factor analysis procedures in SYSTAT. All of these add-modules modules eventually were integrated into, and are still part of the regular SYSTAT package.

More recently StenStat has developed two free-standing Windows applications called MedRoc and ROCstats, both designed to perform receiver-operating-characteristic (ROC) analyses of biomedical research data. More details can be found by clicking the MedRoc link, and/or by clicking the ROCstats link.

In the near future StenStat will be announcing a stand-alone Windows version of an up-dated Testat program that is described above.
