Homework Statement
There is some question, I solved it but am not sure I got the right answer.
Let Y1, Y2... Yn be a random sample of size n from the pdf fY(y;[tex]\Theta[/tex]= [tex]\frac{1}{\Theta}[/tex]*e-y/[tex]\Theta[/tex] , y>0
Let [tex]\Theta[/tex]_hat=n*Ymin is tex]\Theta[/tex]_hat for [tex]\Theta[/tex] ?
Homework Equations
Ymin=n*(1-FY(y))n-1fY(y)
Also, it looks like an exponential distribution.
The Attempt at a Solution
What I need to find is E[n*Ymin]
I get [(-n)/(n+1)]/(1/ [tex]\Theta[/tex] )
Is this the correct answer ?
