Local Dependence Indexes for Item Pairs Using Item Response Theory.
Chen, Wen-Hung; Thissen, David
Journal of Educational and Behavioral Statistics, v22 n3 p265-89 Fall 1997
Four statistics are proposed for the detection of local dependence (LD) among items analyzed using item response theory. Simulation results show that, under the locally dependent condition, the X-squared and G-squared indexes appear to be sensitive in detecting LD or multidimensionality among items. (SLD)
