统计学和机器学习中估计量的偏差(Bias of an estimator)。 在统计学和机器学习里,我们常常需要用一个估计量(estimator)去估计总体的某个参数。例如,用样本均值去估计总体均值。偏差用于衡量估计量与真实参数之间的平均差异程度。 定义公式: 设θ̂是总体参数θ的一个估计量,偏差的计算公式为Bias(θ̂) = E(...

Following the definition of the bias of an estimator in mathematical statistics, we quantify the anchoring bias by\(B_{t}(x,a)=\mathbb {E}[\hat {x}_{t}|x,a]-x\), where\(\hat {x}_{t}\)is a participant’s estimate of a quantityxafteriadjustments, andadenotes the anchor. Fig...
However, the accuracy of the estimator (i.e., its bias) is often ignored. The purpose of the present study is to examine the degree of bias. Using exact calculations based on the binomial theorem, we determined the bias of an estimate of conditional on pC not equal pT, and the bias ...
