未知

These conditions do not relate to the unknown parameters but the dimension of model, so it is easy to apply in practice. Next, we consider the relative efficiency of LSE against the beast linear unbiased estimator.

我们给出了Pitman准则下，最小二乘估计优于Within估计的一个充分条件，最后又得到了广义均方误差意义下两步估计一致的优于Between估计和Within估计的充分条件，并且这些条件只是和模型维数有关而和未知参数无关的一些不等式关系，因此便于实际应用。
