Hi,
I'm trying to find the MM of a Beta(a,b) using the first and second raw moments.
I use
and
I then set those equal to and , respectively, and (try to) solve for a and b.
Does that sound right? (I'm getting stuck.)
Thanks!
you can find the answer at

Note that they use the centered second moment, but you can expand v and use your two sample moments.
