Osteometric Discriminant Analysis
Definition
Multivariate statistical classification of an unidentified bone specimen based on a set of standardised measurements, using reference data from known-species museum collections to calculate the most probable taxon assignment.
- Type
- Multivariate statistical classification method
- Input
- Standardised bone measurements from an unidentified specimen
- Reference data
- Known-species museum collections
- Output
- Most probable taxon assignment
Common questions
How reliable is osteometric discriminant analysis for a fragmentary bone?+
Accuracy depends heavily on how many of the standard measurement landmarks survive on the fragment; a specimen missing key landmarks yields a lower-confidence or unresolved classification rather than a definitive species call.
Does this method distinguish forensic (human) cases from wildlife cases?+
The same statistical approach applies to both, but the reference database used differs: human-vs-nonhuman discrimination draws on comparative skeletal collections, while wildlife species identification draws on faunal reference collections specific to the taxa in question.
