Description

Minimum-number-of-individuals accounting uses paired elements to establish a lower bound within a resolved taxon and context.

Minimum-number-of-individuals accounting uses paired elements to establish a lower bound within a resolved taxon and context.^[1]

Counts from different element types are not simply additive.

When to use MNI from Most Common Element Calculator

Use this tool to apply the stated mni from most common element calculator operation with an explicit input and unit basis.

How to use MNI from Most Common Element Calculator and how it works

Establish the measurement basis and units described above.
Enter actualElementTypeLabels, actualLeftElementCounts, actualRightElementCounts and run the tool.
Read result.elementLowerBounds, result.minimumIndividualsLowerBound using the output meanings below.
If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.

Input field	Meaning	Value type	Requirement
actualElementTypeLabels	Element type labels, on the basis specified in the algorithm.	array of string	required; dense; align related rows as specified; at most 128 strings; 128 UTF-16 units each; further conditions in the algorithm
actualLeftElementCounts	Left element counts, on the basis specified in the algorithm.	array of number	required; dense; align related rows as specified; further conditions in the algorithm
actualRightElementCounts	Right element counts, on the basis specified in the algorithm.	array of number	required; dense; align related rows as specified; further conditions in the algorithm

Require distinct element labels and aligned left/right integer counts 0–10,000. Take the larger side count per element and then the largest element bound overall.

MNI lower bound = max_elements(max(left count,right count))

Apply the declared units, ordering and branch conditions.

Output field	Meaning	Value type
result	Object containing the declared output fields.	object
result.elementLowerBounds	Per-element maximum of left and right counts in label order.	array
result.minimumIndividualsLowerBound	Largest per-element bound; a minimum rather than an exact population count.	number

Limitations and assumptions

The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.

Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A successful false boolean, negative signed difference, empty slice or unresolved tie is distinct from an input error. Very large inputs or outputs may be rejected by shared resource limits.

Alternative or Complementary methods

For a related operation, use Dinosaur Bonebed Monospecificity Percent Checker. A focal taxon's specimen fraction measures its share of a taxonomically resolved bonebed inventory.

For a related operation, use Bioerosion Trace Density per dm2 Calculator. Bioerosion trace density records independently identified traces per inspected surface area.
