Unbiased Estimator
Do you remember that estimator we found in class? The one I didn't check to see if it was unbiased because it required using integration by parts FOUR TIMES? It turns out it's UNBIASED! Do you want to see the computations? Just click this link!
Notes:
- The PDF comes from Exercise 5.2.5 in the textbook, but the exercise only asks you to find the maximum likelihood estimate. It does not ask you to check to see if it is unbiased. (This topic doesn't even come up until Section 5.4.)
- I would never ask you to check for unbiasedness when it is this involved.
- Holy cow! I cannot believe this estimator is unbiased!
