估计的偏差

Bias of an estimator

在统计学中,估计器的偏差是该估计器的预期值与正在估计的参数的真实值之间的差值。 具有零偏差的估计或决策规则被称为无偏差。 否则估计量据说是有偏见的。 统计上,“偏见”是一个关于功能的客观陈述,虽然不是一个理想的财产,但并不是贬义的,不像普通英语中使用“偏见”一词。 偏差也可以相对于中值而不是平均值进行测量,在这种情况下,将中值无偏差与通常的平均无偏性属性区分开。 偏差与一致性相关,因为一致的估计量是收敛的和渐近的无偏差的,尽管一致序列中的个体估计量可能有偏差; 看偏见与一致性。 所有其他相等的,无偏估计器比偏倚的估计器更可取,但实际上所有其他方法都不相等,偏倚的估计器通常用小的偏倚。 当使用有偏估计时,也会估计偏差。 In statistics, the bias of an estimator is the difference between this estimator's expected value and the true value of the parameter being estimated. An estimator or decision rule with zero bias is called unbiased. Otherwise the estimator is said to be biased. In statistics, "bias" is an objective statement about a function, and while not a desired property, it is not pejorative, unlike the ordinary English use of the term "bias". Bias can also be measured with respect to the median, rather than the mean, in which case one distinguishes median-unbiased from the usual mean-unbiasedness property. Bias is related to consistency in that consistent estimators are convergent and asymptotically unbiased, though individual estimators in a consistent sequence may be biased; see bias versus consistency. All else equal, an unbiased estimator is preferable to a biased estimator, but in practice all else is not equal, and biased estimators are frequently used, generally with small bias. When a biased estimator is used, the bias is also estimated.
