For the pdf f(x) = (θ^2+θ)*(x^(θ-1))*(1-x), 0<x<1,

let Y_{1}<Y_{2}<...<Y_{n}denote the corresponding order statistics.

Find β so that W_{n}= (n^β)*Y_{1}converges in distribution.

Find the limiting distribution of W_{n}.

I know that F(x) = (x^θ)(θ-θx+1), so F_{Y1}(y) = 1-(1-(y^θ)(θ-θy+1))^n, but plugging in w/(n^β) for y does not get me anything that I can see would lead to W_{n}converging in distribution.

Any help would be great!
