- To eliminate negative variance from the production plan and actual production. 根据实际生产和计划的差异来消除负面影响。
- In this case optimally weighted LS estimate is not a linear estimate of a parameter given input and observation anymore and can not be compared with linear minimum variance estimate. 在这种情况下，最优加权最小二乘估计变成关于观测和输入的非线性估计，且与线性最小方差估计不可比。
