calc_rank_of_mrca_uncertainty_between

calc_rank_of_mrca_uncertainty_between(first: Union[HereditaryStratigraphicColumn, HereditaryStratigraphicSpecimen], second: Union[HereditaryStratigraphicColumn, HereditaryStratigraphicSpecimen], prior: Literal['arbitrary'], confidence_level: float = 0.95) → int | None

How wide is the estimate window for generation of MRCA?

Calculate uncertainty of estimate for the number of depositions elapsed along the line of descent before the most common recent ancestor with second.

Returns 0 if no common ancestor between first and second can be resolved with sufficient confidence. If insufficient common ranks between first and second are available to resolve any common ancestor, returns None.
