Paper will analyse the GRR layer function by limited state machine theory and divide different running state for each sub-layer .

论文采用有限状态机的设计理论对GRR层进行功能需求分析，划分出各个子层的运行状态。

Same as ridge regression and partial Least-squares regression , GRR mainly applies to multicollinearity and is effective settlement for sample measure less than the number of independent variable .

和岭估计以及偏最小二乘估计一样，广义岭估计主要适用处理病态设计矩阵，并可以有效的解决普通多元线性回归无法解决的问题，如样本个数小于自变量的个数。

Horel and Kennard gave the generalized ridge regression ( GRR ) in 1970.It is a new multivariate analysis method . In recent years it has developed at theory and application rapidly .

广义岭估计是Horel和Kennard（1970）提出的一种新型的多元分析方法，近几十年来，它在理论和应用方面都以得到迅速的发展。

Finally , by GRR verify the test system to determine the stability and reliability . Finally , all the above work managed to increase the test speed as well as lower the test cost while ensuring the product yield and the test accuracy .

最后通过GRR验证来确定整个测试系统的稳定和可靠性最终通过以上的工作，在保证产品良率和测试精度的情况下提高测试速度，降低测试成本。

Then , several polling schemes including PRR , ERR , GRR and DRR are compared . After simulating , we get a result which to be used to conclude that DRR has an excellent performance compared to the others .

根据仿真结果对PRR、ERR、GRR和DRR进行了比较，得出DRR是相对优化的轮询方案。
