Once a linear relation has been derived, the following question arises: given a new value of one of the magnitudes, what value should be assigned to the other magnitude? This is a prediction problem, and the standard approach to solve it is to insert the new value in the linear relation, ignoring the fact that the new value may be affected by error. This approach was questioned by Das et al. (2014)... You do not have access to this content, please speak to your institutional administrator if you feel you should have access.
