Introduction to Propensity Score Matching

Propensity score matching is crucial in epidemiological studies, leveraging observational data for accurate estimations. However, its effectiveness depends significantly on the appropriate model specification.

Study Overview

  • Objective: Compare supervised deep learning models and unsupervised autoencoders for propensity score estimation.
  • Methods: Application of a plasmode simulation with Right Heart Catheterization dataset.
  • Comparison: Evaluated against traditional methods including logistic regression and spline-based approaches.

Key Findings

  1. Performance: Supervised deep learning models showed superior performance in variance estimation.
  2. Bias Levels: They maintained comparable bias to traditional methods.
  3. Real-World Data: Estimates from the supervised model closely matched conventional methods, indicating reliability.

Conclusion
