The Statistical Analysis System (SAS) began as a project at North Carolina State University's agricultural department. It was originally led by Anthony James Barr in 1966, then joined by NCSU graduate student James Goodnight in 1967 and John Sall in 1973. In the early 1970s, the software was primarily leased to other agricultural departments in order to analyze the effect soil, weather and seed varieties had on crop yields. The project was funded by the National Institutes of Health and later by a coalition of university statistics programs called the University Statisticians of the Southern Experiment Stations.
