One approach to using an asymptotic method here would be to reference the
resulting test statistic (-xtlogit-'s likelihood-ratio chi-square, for
instance) against its empirical distribution in simulation under the null
hypothesis using the study's sample sizes and with the observed rho instead
of against the chi-square distribution.  Wouldn't this overcome objections
that an asymptotic method, such as -xtlogit-, doesn't maintain Type I error
rate with small samples?  I wonder how well this approach would be received.
