Phase 3 ships exactly these three tests. Anderson–Darling is the recommended default because it gives good power across the tail region that matters most for capability interpretation.
Members
| AndersonDarling | 0 | The Anderson–Darling test. This is the default for Phase 3 convenience workflows. It gives extra weight to the tails of the distribution and performs well for the sample sizes typical in SPC capability analysis. |
| ShapiroWilk | 1 | The Shapiro–Wilk test. Works best for samples up to a few hundred observations and is widely cited in statistical process control literature. |
| KolmogorovSmirnov | 2 | The Kolmogorov–Smirnov test (one-sample, comparing against a fully specified normal distribution). Suitable when the theoretical parameters are known; otherwise the Lilliefors correction applies. |
