SAS Programs for Generating Winsteps Control Files and Web-Based Presentations
Yu, Chong
Applied Psychological Measurement, v30 n3 p247-248 2006
Winsteps (Rasch Measurement Software and Publications, 2003), as its name implies, is a psychometric program created specifically to compute the step function (Wright & Masters, 1982) for exams carrying partial-credit items. Despite the clarity of the Rasch model (Bond & Fox, 2001) and the availability of rich features in the program, such as the item-person map, Scalogram, and fitness indices, coding the input file for Winsteps, especially the partial-credit key, and interpretation of Winsteps's output could be challenging to novices. This challenge is partly due to the Winsteps's text-based interface. To augment Winsteps, two SAS macros programs were written to aid users by formatting the input file for Winsteps and by adding graphical presentation of the Winsteps item parameter output.
