Replication of Major Profile Patterns in Structural Equation Modeling: Effect of Bootstrapping in a Small Sample.
Kim, Se-Kang
The effect of bootstrapping was studied by examining whether major profile patterns were replicated when sample sizes were reduced. Profile patterns estimated from the original sample (n=645) of the Wechsler Preschool and Primary Scale of IntelligenceThird Edition (WPPSI-III) Standardization Data were considered major profiles. For bootstrapping, the original sample was reduced to n=50, n=25, and n=20. From each reduced sample, profile patterns were extracted and compared to the major profile patterns. Then, the bootstrapping technique was applied to the reduced sample, and the bootstrap correlation matrix was estimated. Using the correlation matrix, profile patterns were estimated, and they were compared to the major profile patterns. To measure correspondence between the major profiles, correlation coefficients were computed. The profile patterns obtained from reduced samples without bootstrapping were poorly matched with the major profiles, whereas the profile patterns from bootstrapped samples were well matched with the major profile patterns. The bootstrapping substantially contributed to replicating major profiles when sample sizes were severely reduced. (SLD)
