Linear least product regressions between estimates of thigh volume and relationship between residuals and the mean of the concurrent estimates in female volleyball players aged 14-18 years (n = 42). Estimates of thigh volume by anthropometry-based new model (TV-NM) and by dual X-ray absorptiometry (TV-DXA, panel a). Differences between anthropometry-based new model (TV-NM) and reference given as dual X-ray absorptiometry (TV-DXA, panel b). The standard error of estimation (Sy∙x), correlation (R and r), coefficient of determination (R 2), upper limits of agreement (ULOA) and lower limits of agreement (LLOA) are also presented
