SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Causal Inference Skill helps you determine whether a chosen action actually caused a measurable outcome, separating true causal effects from mere correlations and random variation.

Core Features & Use Cases

  • A/B testing analysis and power calculations
  • Propensity score methods for observational data
  • Difference-in-Differences and Regression Discontinuity for time-based data
  • Uplift modeling to identify who benefits from interventions
  • Guidance on communicating causal results with viability, caveats, and business implications

Quick Start

Apply a causal inference workflow to your intervention by selecting the appropriate method, designing the study, and interpreting results.

FAQPage Schema
How do I determine if an action caused an outcome using observational data with confounders?

Causal inference separates true impact from correlation in observational data by applying propensity score methods to control for confounders, providing defensible effect estimates and confidence intervals for your business interventions.

What is the best way to analyze an A/B test and calculate its statistical power?

A/B testing analysis calculates the statistical power and effect estimates of experiments, distinguishing the true causal impact of your treatment assignment from random variation to ensure defensible product or marketing insights.

Can I use difference-in-differences for pre/post time-based analysis?

Difference-in-Differences analyzes pre/post time-based data by comparing the changing trends between a treatment group and a control group, isolating the causal effect of an intervention from underlying temporal confounders.

How does uplift modeling identify who benefits from an intervention?

Uplift modeling identifies the specific individuals who benefit most from an intervention by estimating the heterogeneous treatment effect across covariates, allowing you to optimize interventions and maximize causal impact in operations.

When should I use propensity score methods instead of running an A/B test?

Propensity score methods are necessary when you cannot run a randomized A/B test and must rely on observational data, allowing you to balance covariates and mimic random assignment to estimate causal effects despite confounders.

What assumptions and data inputs are required to estimate a valid causal effect?

Estimating a valid causal effect requires clear assignment of treatment, outcome, and covariates, alongside assumptions like no unmeasured confounders; the analysis yields effect estimates, confidence intervals, and explicit analytical caveats.
