To show that an estimator can be consistent without being unbiased or even asymptotically unbiased, consider the following estimation procedure: To estimate the mean of a population with the finite variance σ2, we first take a random sample of size n. Then we randomly draw one of n slips of paper numbered from 1 through n, and if the number we draw is 2, 3,..., or n, we use as our estimator the mean of the random sample; otherwise, we...

Answer true or false: We saw that the sufficient conditions for a consistent estimator included the condition that the limit of the variance of the estimator must be zero as n increases. Since the formula for the variance of our estimated betahat2 does not include an n in our denominator, unlike the variance of the sample mean, we can prove that it is asymptotically unbiased, but we cannot claim that it is consistent.

1.The sample mean is an unbiased estimator for the population mean. This means: The sample mean always equals the population mean. The average sample mean, over all possible samples, equals the population mean. The sample mean will only vary a little from the population mean.

Consider a large population which has population mean µ, and population variance σ 2 . We take a sample of size n = 3 from this population, thinking of the samples as realizations of the RVs X1, X2, and X3, where the Xi can be considered iid. We are interested in estimating µ. (a) Consider the estimator ˆµ1 = X1 + X2 − X3. Is this estimator unbiased for µ? Explain your answer. (b) Find the variance of ˆµ1. (c)...
