    PURPOSE: To prospectively assess the effect of computer-aided detection (CAD) on the interpretation of screening mammograms in a community breast center. MATERIALS AND METHODS: Over a month period, 12, screening mammograms were interpreted with the assistance of a CAD system. Each mammogram was initially interpreted without the assistance of CAD, followed immediately by a .   Statistical methods developed over the last decade for detecting measurement bias in psycho logical and educational tests are reviewed. Earlier methods for assessing measurement bias generally have been replaced by more sophisticated statistical techniques, such as the Mantel-Haenszel procedure, the standardization approach, logistic regression models, and item response theory .

Test purchasers are responsible for maintaining the security of the test content. To avoid inadvertent disclosure of secure test content, test materials (e.g., tests, administration manuals, scoring guides) should be kept separate from patient records, and test publishers can facilitate this process by creating individual record forms (e.g., answer sheets) that do not include test content.

Computer adaptive test (CAT) and item-response theory (IRT) techniques are currently being used to develop a new generation of health outcome instruments that enhance usability in a busy clinical or research setting.

The total number of fuzzy if-then rules is 5 n in the case of the n-dimensional pattern classification is impossible to use all the 5 n fuzzy if-then rules in a single fuzzy rule base when the number of attributes (i.e.
