Derive the Bayesian point estimates of the return to education under quadratic, asymmetric linear (with c2 = 2c1) and absolute (as d ! 0) losses. Under quadratic loss, the optimal point estimate is the posterior mean, E( 1jy). Thus, b1 = :091. is the optimal point estimate under this loss function.

point estimate of a parameter θ is a value (based on a sample) that is a sensible guess for θ. point estimate is obtained by a formula (“estimator”) which takes the sample data and produces an point estimate. Such formulas are called point estimators of θ. Different samples produce different estimates, even though you use the same estimator.

Besides a point estimate of the area, an interval estimate is often required to express magnitude and uncertainty. In this paper we perform a computational analysis of common AUCPR estimators and their con dence intervals. We nd both satisfactory estimates and in-valid procedures and we recommend two simple intervals that are robust to a variety of …

Since the log is monotone, the maximum is the same. Use the derivative to nd potential MLE. Use the double derivative to con rm ...
