  The time series of the number of hurricanes per year in the Atlantic basin
shows a clear change of level between 1994 and 1995. The time series of the
number of hurricanes that make landfall in the US, however, does not show the
same obvious change of level. Prima-facie this seems rather surprising, given
that the landfalling hurricanes are a subset of the basin hurricanes. We
investigate whether it really should be considered surprising or whether there
is a simple statistical explanation for the disappearance of this change-point
at landfall.
