It stands for Minimum Variance Lucky Seven, and is calculated as B* = 7. Since Var(7) = 0, it works perfectly for h=1. Now, true, it *may* be biased, but we don't know whether or not it's biased without knowing the parameter B.Nick Rowehttps://www.blogger.com/profile/04982579343160429422noreply@blogger.comtag:blogger.com,1999:blog-2198942534740642384.post-70925039580765395782015-09-21T14:28:02.744-07:002015-09-21T14:28:02.744-07:00Not quite - the answer is going to depend n an unk...Not quite - the answer is going to depend n an unknown parameter.Dave Gileshttps://www.blogger.com/profile/05389606956062019445noreply@blogger.comtag:blogger.com,1999:blog-2198942534740642384.post-46405369316496860642015-09-21T13:47:03.547-07:002015-09-21T13:47:03.547-07:00Hi Dave: Is the answer no because you don't kn...Hi Dave: Is the answer no because you don't know the bias of B* until after you solve for h ? So, it's a circular<br />problem ? Just a guess. Thanks.<br />mark leedshttps://www.blogger.com/profile/13213841692738932471noreply@blogger.com
