In the following,a new strategy named hierachical robust linear prediction was proposed in which two methods were made use of at the same filtering process.

In this paper, the method of calculating rock shear strength value, C,f with the M robust estimate is presented, the calculating model and method are given.

Summing up the basic theories of the robust estimates for linear parametric models,this paper discussed the determination method of the weight-factor for M estimates,put forward the robust estimates of the semiparametric regression model,and derived the basic formulae .

In this paper,based on the fact that nonnormal values usually exist in the observed values, and making use of the thought of robust estimate in statistics,we construct new square error function,and get the new BP neural network algorithm.

And it not only raises the accuracy but also make the error gradually converge,through measuring uncertainty of robust M estimation method correcting data.

Using PCSE robust estimation, it finds that there exists positive relationship between globalization and pollution, and China gains scale effect, technical effect, structural effect and factor endowment.
