Implementation
Lifescio validates inputs and formats results; listed functions are the principal calculation routines, not an exhaustive transitive dependency list.
- scipy 1.15.3: scipy.stats.f.{pdf/pmf;cdf;sf;ppf;mean;var}
These are pinned library versions; saved results record the versions actually used at runtime.
