Apply propensity score methods, instrumental variables, difference-in-differences, and regression discontinuity designs for causal identification
What this skill does
# Causal Inference Methods Skill Apply advanced econometric and statistical methods for causal identification in observational data. ## Overview The Causal Inference Methods skill enables application of propensity score methods, instrumental variables, difference-in-differences, regression discontinuity designs, and other quasi-experimental approaches for causal identification in observational social science data. ## Capabilities ### Propensity Score Methods - Score estimation - Matching algorithms - Inverse probability weighting - Doubly robust estimation - Balance assessment ### Instrumental Variables - Instrument identification - Relevance testing - Exclusion restriction - Two-stage estimation - Weak instrument diagnosis ### Difference-in-Differences - Parallel trends assessment - Treatment effect estimation - Staggered adoption designs - Heterogeneous effects - Robustness checks ### Regression Discontinuity - Sharp RD design - Fuzzy RD design - Bandwidth selection - Local polynomial estimation - Validity testing ### Design Considerations - Identification strategy - Assumption testing - Sensitivity analysis - Effect heterogeneity - Interpretation limits ## Usage Guidelines ### When to Use - Estimating causal effects - Evaluating interventions - Analyzing policy impacts - Exploiting natural experiments - Addressing selection bias ### Best Practices - Justify identification strategy - Test assumptions - Report sensitivity analyses - Acknowledge limitations - Pre-register when possible ### Integration Points - Quantitative Methods skill - Program Evaluation skill - Systematic Review skill - Policy Communication skill ## References - Propensity Score Analysis process - Natural Experiment Analysis process - Quasi-Experimental Design process - Causal Inference Analyst agent

venue-templates
IncludedAccess comprehensive LaTeX templates, formatting requirements, and submission guidelines for major scientific publication venues (Nature, Science, PLOS, IEEE, ACM), academic conferences (NeurIPS, ICML, CVPR, CHI), research posters, and grant proposals (NSF, NIH, DOE, DARPA). This skill should be used when preparing manuscripts for journal submission, conference papers, research posters, or grant proposals and need venue-specific formatting requirements and templates.
let-fate-decide
IncludedDraws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
