Analyzing Paul the Psychic Octopus's football predictions using Bayesian statistics and probability theory.
Author's 2014 review: writing a data science book from scratch in Python and preparing for/starting a software engineering job at Google.
A technical guide to Dixon's Q test for identifying outliers in small datasets, including its method, application, and criticisms.
Explores the critical difference between frequentist confidence intervals and Bayesian credible regions, arguing why frequentism often fails scientific inquiry.
A data scientist analyzes Seattle's bicycle counter data using Python to determine if cycling is truly increasing or just affected by good weather.
Explores the statistical power of monotonicity vs. smoothness assumptions in modeling, analyzing their asymptotic and finite-sample impacts.
A practical introduction to the philosophical and practical differences between frequentist and Bayesian statistics, with Python examples.
A critique of a proposal to lower the p-value threshold for statistical significance from 0.05 to 0.005, arguing it addresses symptoms, not root causes.
Explores the concept of 'barren proxies' in causal inference, arguing that measurement reliability is more critical than the proxy's barrenness.

Argues for the importance of statistical theory in data science, using examples from medical research to show where abstract theory solved practical problems.
A critique of common pitfalls and unproductive patterns in statistics research presentations, aimed at improving academic discourse.
Explores the equivalence between causal graphs and counterfactual reasoning in statistics, simplifying the connection between two major causal inference frameworks.
Examines statistical challenges with the causal Markov and faithfulness properties, focusing on measurement error's impact on causal inference.
Explores the concept of 'error' in regression models, clarifying when it represents measurement error versus model prediction error.
