Statistical Tricks
Interactive visualizations of key statistical concepts.
A collection of interactive visualizations for key statistical and econometric concepts. Each tool is designed to build intuition โ move the sliders, run simulations, and watch the theory come alive.
Probability & Distributions
Central Limit Theorem
Watch a Bernoulli(p) distribution converge to a Gaussian as the number of repetitions grows. Adjust p, n, and sample size in real time.
Interactive ยท Simulation Law of Large Numbers
Watch K independent running averages converge to ฮผ as n grows. Choose Bernoulli, Uniform, or Exponential and animate the convergence.
Interactive ยท Simulation Common Distributions
Explore the shape, moments, and relationships of key probability distributions.
Coming soon Causal Inference & Quasi-Experiments
Difference-in-Differences
Visualize the parallel trends assumption, treatment effects, and what violations look like.
Coming soon Regression Discontinuity
Explore how RDD identifies causal effects at a threshold, with bandwidth and smoothing controls.
Coming soon Instrumental Variables
See how a valid instrument isolates exogenous variation and what weak instruments do to estimates.
