# Sample Data: Waka Trees

Locations of trees recorded at Waka National Park, Gabon, annotated with diameter (in centimeters) marks

## Details

Locations of trees recorded at Waka National Park, Gabon, in the observation region Rectangle[{0., 0.}, {100., 100.}] meters, annotated with diameter (in centimeters) marks.

## Examples

### Analysis (4)

Compute probability of finding a point within given radius of an existing point - NearestNeighborG is the CDF of the nearest neighbor distribution:

 In[7]:=
 Out[7]=
 In[8]:=
 Out[8]=
 In[9]:=
 Out[9]=

Mean distance between a typical point and its nearest neighbor (for positive support distribution can be approximated via a Riemann sum of 1-CDF):

 In[10]:=
 In[11]:=
 Out[11]=

Test for complete spacial randomness:

 In[12]:=
 Out[12]=

Fit a Poisson point process to data:

 In[13]:=
 Out[13]=
