Query: Least Product Relative Error Estimation   A least product relative error criterion is proposed for multiplicative
regression models. It is invariant under scale transformation of the outcome
and covariates. In addition, the objective function is smooth and convex,
resulting in a simple and uniquely defined estimator of the regression
parameter. It is shown that the estimator is asymptotically normal and that the
simple plugging-in variance estimation is valid. Simulation results confirm
that the proposed method performs well. An application to body fat calculation
is presented to illustrate the new method.
