How To Show That An Estimator Is Unbiased. Is a linear estimator then is easily seen if we switch to matrix notation. ( x n − x ¯) − 1] t, the vector of weights, so that.

Μ obs ∗ = x ¯ = ( x 1 + x 2 + ⋯ + x n) / n. Let y = 1 k (x 1 + + x k) be the average of x To show that the sample maximum xmax=maxni=1{xi} is an unbiased estimator of θ you would need to show that e(xmax)=θ.
