Summary of equations used in this study, taken from Andrews ([28, pp. 45–90] and table 3.2 and 3.9–11 in [28]).
| equation (X 100%) | full term | explanation | elements considered |
|---|---|---|---|
| Ri = NISPi / (MNI × Ei) | relative abundance | ratio of a specific element NISP (NISPi) to expected anatomical elements numbers (MNI multiplied by a number of elements in a typical skeleton, Ei) | BONES: (Ei = 2) maxilla, mandible, scapula, pelvis, humerus, ulna, radius, femur, tibia, calcaneus, talus, (Ei = 36) vertebra, (Ei = 20) metapodial, (Ei = 56) phalange; LOOSE TEETH: (Ei = 12) molars, (Ei = 4) incisors |
| ΣRi/nR | average relative abundances | ratio of the sum of relative abundances (ΣRi) to the number of relative abundances present (nR) | as in relative abundances, either all or excluding loose teeth |
| pc × 8 / c × 5 | full index of postcranial (pc) to cranial (c) elements | pc = NISP(femurs + humeri + tibiae + radii + ulnae); c = NISP(mandibles + maxillae + isolated molars) |
|
| pc / c | simple index of postcranial (pc) to cranial (c) elements | pc = NISP(femurs + humeri); c = NISP(mandibles + maxillae) |
|
| dist / prox | index of distal (dist) to proximal (prox) limb elements | dist = NISP(tibiae + radii); prox = NISP(femurs + humeri) |
|
| T(isolated) / T(missing) | isolated incisors/molars | index of isolated teeth against empty alveolar spaces (i.e. missing teeth); separately for molars and incisors | T(isolated) = NISP(isolated teeth); T(missing) = Count of empty alveolar spaces found |
| T(broken) / T(all) | broken incisors/molars | index of broken teeth against all teeth found; separately for molars and incisors | T(broken) = NISP(broken isolated teeth) + Count of broken teeth in situ; T(all) = NISP(isolated teeth) + Count of all teeth in situ |
