Standardized Extended Caution Indices and Comparisons of Their Rule Detection Rates.
Tatsuoka, Kikumi K.; Tatsuoka, Maurice M.
Several extended caution indices (ECIs) have been introduced earlier as a link between two distinctly different approaches: one based on standard statistics and the other, a model-based approach, utilizing item response theory (IRT). Expected values and variance of some ECIs are derived and their statistical properties are compared and discussed. Then, standardized ECIs are introduced and their distributions are investigated. It turns out that the standardized ECIs fit normal distributions well. A comparison of detection rates among appropriateness measures based on IRT theory is carried out with the signed-number data set. There is no noticeable difference in their detection rates using the 80 percent intervals. (Author)
