摘要
M-estimation of the multiple linear regression model under restrictions on the parameters is considered. Using a penalty function approach an iterative procedure for obtaining the estimates is proposed. The iterations are based on an iterative reweighted least squares procedure to which a modification for the restrictions is added. The influence function for the restricted estimator is derived. It is finally noted that the penalty function approach can be used to define a ridge type M-estimator.
