" It uses the delta-method estimate for the variance of
exp(b)."


The variance/sd did, however, coincide with the one returned by -xtmelogit-.
Thanks for the advice on the endpoints anyway...

Martin, -nlcom- doesn't invert the endpoints of the log-scale
interval. It uses the delta-method estimate for the variance of
exp(b).   It's not a bug, but a trade-off for the great generality of
expressions that -nlcom- can take.
