analysis (PCA) is used as a dimensionality-reduction method, and a clustering algorithm is used to classify reconstruction … network, dimensionality reduction allows measuring of the extent to which the network's main connective features (i.e. the … structure) deviate from those regarded as typical. The key to dimensionality-reduction methods is the ability to reconstruct …

This dissertation compares the parameter estimates obtained from two item response theory (IRT) models: the 1-PL IRT model and the MC1-PL IRT model. Several scenarios were explored in which both unidimensional and multidimensional item-level and personal-level data were used to generate the item...
