Abstract | Local dependence (LD) for binary IRT models can be diagnosed using Chen and Thissen's bivariate X[superscript 2] statistic and the score test statistics proposed by Glas and Suarez-Falcon, and Liu and Thissen. Alternatively, LD can be assessed using general purpose statistics such as bivariate residuals or Maydeu-Olivares and Joe's M[subscript r] statistic. The authors introduce a new general statistic for assessing the source of model misfit, R[subscript 2], and compare its performance to the above statistics using a simulation study. Results suggest that the bivariate and trivariate X[superscript 2] statistics have unacceptable Type I error rates. As for the remaining statistics, if their computation involves the information matrix (bivariate residuals and score tests), they show good power; if not (M[subscript r] and R[subscript 2]), they lack power. Of course, the performance of the bivariate residuals and score tests depends on how the information matrix is approximated. (Contains 9 tables.) (As Provided). |
