Takeaways:

• CFA is commonly used in psychometrics to validate theoretical constructs.
• Theoretical structure is crucial in confirmatory factor analysis.
• Bayesian approaches offer flexibility in modeling complex relationships.
• Model validation involves both global and local fit measures.
• Sensitivity analysis is vital in Bayesian modeling to avoid skewed results.
• Complex models should be justified by their ability to answer specific questions.
• The choice of model complexity should balance fit and theoretical relevance. Fitting models to real data builds confidence in their validity.
• Divergences in model fitting indicate potential issues with model specification.
• Factor analysis can help clarify causal relationships between variables.
• Survey data is a valuable resource for understanding complex phenomena.
• Philosophical training enhances logical reasoning in data science.
• Causal inference is increasingly recognized in industry applications.
• Effective communication is essential for data scientists.
• Understanding confounding is crucial for accurate modeling.
