Parceling is referred to as a procedure for computing sums or average scores across multiple items. Parcels instead of individual items are then used as indicators of latent factors in the structural equation modeling analysis (Bandalos...
In education and psychology, exploratory factor analysis (EFA) is mainly used in scale development or refinement. To select a final EFA model, researchers take into account not only the number of factors, but also parameter estimates...
Structural equation modeling (SEM) refers to statistical analyses of the relationships among observed and latent variables based on hypothesized models. In reality, proposed models are rarely perfect, specification search is conducted to...
In structural equation modeling (SEM), researchers use the model chi-square statistic and model-fit indexes to evaluate model-data fit. Root mean square error of approximation (RMSEA), comparative fit index (CFI), and Tucker-Lewis index ...
The nonequivalent-groups anchor-test (NEAT) data-collection design is commonly used in large-scale assessments. Under this design, different test groups take different test forms. Each test form has its own unique items and all test...
The problem of class imbalance has become frequent, and missing data also are often a predicament in the social sciences. In the literature, the two problems have been debated substantially and separately. Class imbalance has been shown...
In factor analysis, determining the number of factors underlying measurement indicators is important. An incorrect decision on the number of factors may mislead practitioners in terms of estimating parameters in factor analysis, ...
