Abstract
Item response modeling is used for analyzing psychometric data, quality of life data, and can even be used analyzing diagnostic tests. It may provide better precision than does the classical linear analysis. This chapter assesses how it works. The LTA-2 software program of Uebersax is a free software program convenient for the purpose. It works with the areas under the curve of statistically modeled best fit Gaussian curves of the data rather than a histogram of the data, but, otherwise, it is similar to the pocket calculator method.
