Interactive Excel Tool for Computing, Assessing, and Using EmP Ws Equations

Abstract Recent evaluations of the regression-line percentile (RLP) method for developing standard weight (Ws) equations urged a change in standard practices. We recommend a change to the empirical-percentile (EmP) method, which is not prone to length-related bias associated with extrapolating beyond the range of the data. To enable consistent and valid interpretation of relative weight, […]
