What distribution is that?
PS what the heck is going on with all this spam?
It's just a HW prob from my graduate level inference class. We are asked to show that 2x̄ is an unbiased estimator of theta, but when I take E[2x̄] I can only simplify it down to 2E[X]... so I was hoping to find the distribution name to simplify things a bit.
Or else, how else would I find E[x]? The MGF I suppose?
