Abstract:

Suppose that I have a coin with unknown probability $p$ of heads. One way to estimate $p$ is to flip the coin $k$ times, count the number of heads, and divide by $k$. While this is in some sense the more efficient method, the relative error in this approach depends on $p$, the unknown quantity. In this talk I will show how to build $\hat p$, an estimate for $p$, such that the relative error in the estimate, $\hat p/p - 1$, is completely independent of $p$. Along the way we'll use an interesting fact about generating functions for random sums of random variables.
