Panel regression formulas for estimating stature and body mass from immature human skeletons: a statistical approach without reference to specific age estimates

► We examine the utility of panel regression for prediction equations in anthropology. ► We provide one formula to estimate stature from femoral diaphysis length. ► We provide three formulas to estimate body mass using different skeletal measures. ► Panel regression accurately predicts body size compared to commonly used equations. ► Final stage error is reduced because independent age estimates are not required.
