Rasch Model Analysis with the BICAL Computer Program.

摘要

The Rasch Model is the mathematical formulation of any measurement situation, either physical or psychological, for which the relevant statistic can be expressed in terms of the number of successes (or number of targets hit, items correct or marks exceeded). The model specifies an efficient and reasonable way to make objective inferences from observations to variables. The concept and development of the model is discussed, emphasizing application to measurment of psychological variables. The BICAL program, a FORTRAN program to test the parameters, is described, with application to military police marksmanship data used as an illustration. (Author)
