This function can be used to estimate age-at-death with the choice of using Middenbeemster as the default reference population or incorporating a different reference population.
bamsaur( wear, ref_pop = NULL, degree = 2, interval = "prediction", level = 0.68, ... )
| wear | Numeric. Dental wear scores for age estimation. Can be a single number or an array. |
|---|---|
| ref_pop | Reference population used to estimate age from wear scores. Default is the built-in "MB11" population. Other reference populations can be supplied with a data frame/matrix containing ages-at-death in the first column and wear scores in the second column. |
| degree | Numeric. Degree of polynomial for the model. 1 = linear regression, 2+ = polynomial regression. Default is 2. |
| interval | Character. Type of interval for age estimates. Options are "prediction" and "confidence". |
| level | Numeric. Level for the confidence and prediction intervals. Must be a number between 0 and 1. |
