Moberg, et al., (1980) adaptive M-estimation procedure depends heavily on the measures of the skewness and tailweight . The sensitivity of Moberg, et al. procedure to skewness measure was shown using a particular bimodal distribution for errors in linear regression. Properties of this particular distribution have been exploited and investigated; for this type of errors distribution we developed an alternative procedure for choosing the Y function. Results and performance of the procedure is presented via simulation.
