是否有可能(一个估计量)是无偏却不一致的？
Is it possible for an estimator to be unbiased but inconsistent?
虽然并不是所有的有用的估计量是无偏的，但是，一致性则是经济学家对估计量的最低要求。
While not all useful estimators are unbiased, virtually all economists agree that consistency is a minimal requirement for an estimator.
当估计量无偏时，数字估计值也常叫做无偏的。
When the estimator is unbiased, the numerical estimate is frequently also called unbiased.
