Figure 2.2An unbiased estimator has a sampling distribution that is centered over the population parameter. Yis unbiased because its sampling distribution is centered over m.
Figure 2.3The estimator is asymptotically unbiased; its sampling distribution becomes centered over s2 as n→∞.
Figure 2.4The variance of Ydecreases as the sample size increases.
Figure 2.6Simulated samplingdistributions (uniformpopulation).
Figure 2.8The least squares estimator is the value of m that minimizes the sum of squares function S.
