grazing

<p>In this experiment, the density of understorey birds at
a series of sites in two areas either side of a stockproof fence
were compared. Once side had limited grazing (mainly from native
herbivores), and the other was heavily grazed by feral herbivores,
mostly horses. Bird counts were done at the sites either side of
the fence (the Before measurements). Then the herbivores were
removed, and bird counts done again (the After measurements).
The measurements are the total number of understorey-foraging
birds observed in three 20-minute surveys of two hectare quadrats.</p>

datasets

Implementation of new discrete statistical distributions. Each distribution includes the traditional functions as well as an additional function called the family function, which can be used to estimate parameters within the 'gamlss' framework.
