Recovering a distribution from sample averages?
I figured this out right after I posted it.
From observing $\bar{x_1},...,\bar{x_n}$ (for large enough $n$) I can compute the characteristic function
$$\psi(\bar{X},t) = \mathbb{E}[e^{it\bar{X}}]. …

I'm working on a problem where I have $n^2$ real numbers $x_{11},...,x_{nn}$, all drawn i.i.d. from the same distribution $F$. I don't observe each $x_{ij}$, but I do observe the $n$ means:
$$\bar{x} …
