WebFor an estimator θ ^ n, the mathematical illustration of statistical bias can be defined as. (22.10.2) bias ( θ ^ n) = E ( θ ^ n − θ) = E ( θ ^ n) − θ. Note that when bias ( θ ^ n) = 0, the expectation of the estimator θ ^ n is equal to the true value of parameter. In this case, we say θ ^ n is an unbiased estimator.
