Model Weights Analysis and Structural Model Refinement

The Model Weights Analysis and Structural Model Refinement chapter extends the validation process of the Individuality Assisted Estimation model using Partial Least Squares Structural Equation Modeling (PLS-SEM). This chapter evaluates the overall model structure, assessing whether it effectively captures the recorded data to understand how individuality influences Quality of Experience ratings. It quantifies the strength of relationships within the model and explores potential refinements to optimize its alignment with the data. By utilizing direct estimations of stimulus quality and focusing on data from conversation experiments, the chapter provides a comprehensive analysis of model fit and structure. The findings highlight the significant predictors and refine the model by removing unsupported constructs, resulting in a streamlined version that better represents the data. This refined model emphasizes traits, states, and reactions, with a focus on conversational interactivity dimensions, ensuring robust and reliable predictions of experience ratings.
