Almost no real-world data is Normal. Latency is right-skewed. Error counts are Poisson. Click rates are Bernoulli. Yet every classical statistical tool — t-test…
You want to know a model's true generalization accuracy — its expected performance on all possible test inputs. You cannot observe this directly. You have six C…
A model achieves 83.8% mean CV accuracy. The current baseline is 80%. Is 83.8% genuinely better, or is that 3.8-percentage-point gap noise from six folds? You c…
The p-value might be the most misunderstood number in statistics. It appears in every A/B test, every model evaluation, and every research paper — yet practitio…
Historical benchmarks show the baseline model achieves 80% accuracy with known σ=0.05 (computed from millions of CV runs). Your new model achieves x̄=0.838 acro…
