The graph works fine, although I would like to have smoother
confidence limit lines and a logaritmic y-scale to better show the
effect at the smaller number of operations.
I wonder why you are sceptic to use such a graph to visualize the
differences between hospitals?
--------------------------------------------------------------
It is easy to use a log y-scale, by including a -yscale(log)- option.
However, you get a problem for hospitals with no deaths because log(0)
is minus infinity.
Actually I think the general idea is good, my scepticism is due to
what I consider a slight abuse of the term "confidence interval".
