Required inputs
- Observed count matrix — 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 formulas and summaries over NumPy arrays. Sample variances use ddof=1; custom formulas are described in the method help.
- numpy 2.2.6: numpy.outer, numpy.sum
These are pinned library versions; saved results record the versions actually used at runtime.
