Deflation-Corrected Estimators of Reliability.

ABSTRACT: Underestimation of reliability is discussed from the viewpoint of deflation in estimates of reliability caused by artificial systematic technical or mechanical error in the estimates of correlation (MEC). Most traditional estimators of reliability embed product-moment correlation coefficient (PMC) in the form of item-score correlation (Rit) or principal component or factor loading (λ _i ). PMC is known to be severely affected by several sources of deflation such as the difficulty level of the item and discrepancy of the scales of the variables of interest and, hence, the estimates by Rit and λ _i are always deflated in the settings related to estimating reliability. As a short-cut to deflation-corrected estimators of reliabili
