I examined the distributions of bootstrapped p-values for zero-mean shifted Poisson distributions ($X + \lfloor\lambda\rfloor \sim \text{Poisson}(\lambda)$) and found good power even with moderately small sample sizes. E.g., with two datasets of $100$ values each, $\lambda=1$ is discriminated from $\lambda=1.4$ with 50% power at $\alpha=.05$. These chi-squared statistics do not appear to have chi-squared distributions, whence the need to bootstrap the p-values. | |
