Homework Statement
A random sample of size 2, Y1 and Y2, is drawn from the pdf
fY(y;[tex]\vartheta[/tex])=2y*[tex]\vartheta[/tex]2, 0<y< 1/ [tex]\vartheta[/tex]
What must c equal if the statistic c(Y1+2Y2) is to be an unbiased estimator for 1 / [tex]\vartheta[/tex]
Homework Equations
The Attempt at a Solution
I tried to find the E[c(Y1+2Y2)] but don't really know how to reach 1 / [tex]\vartheta[/tex]
There is also the equation of the Ymax
maybe I should set them equal ? but how to get rid of Y1 and Y2 ?
Thanks.
