The question 2 of the attachment, Can't type now , Sorry, again this is also for Bill
These questions are on behalf of Bill who needs urgent help but cant start threads/post for some reasons
Question 1 : Suppose that
Consider the following estimators for .
and
Calculate MSE of those estimators and discuss which one is closer to
.
HINT: If
than
Note: MSE - Mean squared Error
iid = independent and identically distributed
--= ~ and iid is above it
There is question #2 about the Gamma distribution.
a) its a F-distribution where
Z=(X/k) over (Y/m), but in this question I dunno what k and m are??? and even if Z is correct
b) NO CLUE
c) I found this:
Estimate + - (critical value)*(standard error)
where the critical value comes from the relevant distribution e.g. Normal, t, chi-square, F, Gamma, and so on.
However, the standard error will vary depending on statistic being estimated.
Of which I don't know what is what.
Am I out of it? I have little idea of what is going on
This thread is relavant to question 2: http://www.mathhelpforum.com/math-he...on-ratios.html
