DBSML
Definition
Detroit-Bone Sex/Maturity Logic: a logistic-regression-based classification system for sex estimation from cranial and postcranial linear measurements, developed at Wayne State University, providing a posterior probability of male or female from FADB-validated reference data.

Common questions
How does DBSML's logistic-regression output differ from a traditional binary sex-estimation call?+
Rather than a simple male-or-female classification, DBSML produces a posterior probability for each sex based on the input measurements, letting the analyst report the strength of the classification and flag cases near the decision boundary as indeterminate rather than forcing a confident-sounding binary answer from ambiguous measurements.
Why does DBSML rely on FADB-validated reference data specifically?+
Using a large, population-representative validated reference database like FADB reduces the risk that the classification model is biased toward the ancestry or body-size range of a narrower original training sample, which matters because skeletal dimensions used for sex estimation vary across populations.
