Multi-step Method for Resolving Ill-conditioned Problem of Gauss-markov Model

摘要：

　　Toward the ill-conditioned Problem of Gauss-Markov model,analyze the causes and all kinds of methods,emphatically research the computational process of Two-Step method.Extending and simplifying Two-Step method,give a new method for solving ill-conditioned problem,multi-step method.Detailedly expound the computational process of it.Simulate an ill-conditioned model and compute its parameter estimations by some different methods.Finally through analog computation,venify the feasibility and quality of multi-step method.
