(5 points) Given a sample X; = {2,}, define gi(2) = r. That is, the estimator gi estimates any example x as the r value of the first instance in the (unordered) dataset -X. What can you say about the bias and variance of this estimator? Describe by comparing against the benchmarks: 9i(2) = 2 and gi() = Eir/N. What if the sample is ordered so that gi() = mint how would the bias and variance compare against the two benchmarks? (5 points) Given a sample X; = {2,}, define gi(2) = r.
