Abstract：In penalized least squares estimation with the semiparametric model，the key is how to calculate regularization parameter effectively.An optimization method with a new model of the penalized least squares,was proposed for calculating the regularization parameter based on criteria of the generalized cross validation and L curve.The results of simulation calculation show that themethod is more effective for calculating regularization parameter.
