This function computes the tuning constant that yields an MM-regression estimator with a desired asymptotic efficiency when computed with a rho function in the corresponding family. The output of this function can be passed to the functions lmrobdet.control, scaleM and rho.
moptv0(e)A vector with named elements containing the corresponding tuning parameters.
the desired efficiency of the corresponding regression estimator for Gaussian errors
