...ve binomial model, the mean is often times to
the right of the most likely value, so I'd like to ask how one would go
about predicting the most likely value.
Thanks in advance !

Plotting series with no data in xyplot
...to think about it, it might be rather complex because you'd need to tell
xyplot what granularity you'd like to not connect (e.g. 5 hours in a
row, 4 days in a row, etc).
Any help would be much appreciated !
