Abstract :
Under the morbid Gauss-Markov model, Ridge estimation(RE) is very effective in data processing. But the determination of ridge parameters is an issue. Ridge estimation shared the difficulty of the determination of ridge parameters. This paper brings about a method to solve the above problem, which is called generalized partial ridge estimation(GPRE). With it we can obtain the optimal solution to the GPRE directly and the ridge parameters are not to be calculated all. The method proposed in this paper provides a more effective technical to the biased estimation than ridge estimation. The mean square error of GPRE is smaller than RE and the mean square residual is larger.
