• More Data, More Confident, Still Wrong: The Table 2 Problem at Scale

  1 Jul, 2026

  A simulation study showing that as sample size grows, coverage rates for confounded control-variable coefficients collapse toward zero — the Table 2 fallacy gets worse with more data, not better.

• Collinearity Doesn't Break Your Model — It Tells You What Your Data Can't Separate

  30 Jun, 2026

  A high VIF isn't a technical failure to fix — it's a signal that your data can't distinguish two effects. The right response is better data or informative priors, not variable deletion.

• Simulation-Based Calibration: The Missing Test in Your Bayesian Workflow

  29 Jun, 2026

  Passing R-hat and ESS tells you the sampler converged — it says nothing about whether the inference is correct. Simulation-Based Calibration is the test that checks the inference itself.

• Read the Diagnostics First

  28 Jun, 2026

  R-hat, ESS, and divergences are not bureaucratic hurdles before you report a ROAS — they're the sampler telling you whether its output is valid. Here's what each one actually measures and what it reveals when it fails.
