  • Causal Inference

    Causal Inference

    Causal inference provides a framework for deducing the relationship between cause and effect using empirical data. It employs a variety of rigorous methods to ensure the validity of its findings, making it indispensable in fields such as policy evaluation, economics, and healthcare.

  • Null Hypothesis

    Null Hypothesis

    In statistical hypothesis testing, the null hypothesis asserts a lack of effect and serves as a baseline for evaluation. Specific tests are employed to assess evidence, leading to either the rejection or the failure to reject this initial assumption. This methodology is pivotal in both scientific inquiry and rational decision-making.
