On the second question, check out -statsby-.
On the first, see also -concord- (-findit concord- for locations).

Dear Statalisters,
I am struggling with batplot (quiet successfully I must say) and I
have a couple
of questions regarding the use of this command:
1) Is there any way to modify the Y axis label options so that the
"dashed"
green line would be centered to 0 value on Y axis and the limits of
agreements
would be symmetric around the zero then ? Using the ylab options I
can change
the label but not the position of the graph...
2) The "grey" area defined by the B-A plot (using the notrend
option) defines
95% limits of agreeement, am I correct ?
3) My Mentor here asked me to compute the "Bias" for the inter-
observer
agreement in the same dataset of measures. I am assuming this is the
simple
coefficient of variation (obtained as 100 * SDdiff / Mean-diff) am I
correct ?
I have also another question, totally unrelated to B-A plots:
I have to run several simple regression models and would like to
automatically
group results
