| Outline of Final Research Achievements |
When conducting longitudinal research, investigation of between-individual differences in patterns of within-individual change can provide important insights into a variety of typical developmental and growth patterns. We focused on a model-based exploratory data mining technique called structural equation model trees (SEMTrees). SEMTrees is a technique that classifies participants into subsets (classes) by recursively partitioning data based on the values of the observed covariates such as age, sex and personality of individuals. In the present research we investigated the performances of SEMTrees under various research designs including an influence of possible model misspecifications, and also investigated a relation between the sample size and precision of classification under various template models specified.
