Which rule do you recommend? I chose Sturges' rule because it
was the simplest of the three. I'm happy to use Scott's rule or
Freedman and Diaconis's rule, but I do not know which one to
choose. Which one do you recommend?
There is also the iterative method described here:

This one would use a lot more CPU time, but if it is
significantly better then we could implement it anyhow.
