Scheffé test
Hypothesis tests · Method and input reference
Each line is a group. Repeated measures and Friedman require the same subjects in matching positions. Dunnett uses the first line as control. Parametric ANOVA assumes normal independent errors; repeated ANOVA assumes sphericity. Synthetic example: Four independent treatment arms, 40 blood-pressure observations per row (mmHg); arm 1 is control. Variances differ between arms.

Required inputs
- Groups (one group per line) — Numeric observations; preserve the row and column structure described above.
Review missing values and data coding before running. Sample inputs are synthetic teaching examples.
Implementation
Lifescio implements the method-specific formula using the listed SciPy distribution functions and NumPy array arithmetic. See method help for assumptions.
- scipy 1.15.3: scipy.stats.f.sf, scipy.stats.f.ppf
These are pinned library versions; saved results record the versions actually used at runtime.
