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.
