Simulates Strauss Spatial Point Process
Simulates Strauss spatial point process.
Strauss(n, c=0, r)
n |
number of points |
c |
parameter |
r |
inhibition distance |
Uses spatial birth-and-death process for 4n steps, or for 40n steps
starting from a binomial pattern on the first call from an other function.
Uses the region set by ppinit or ppregion.
list of vectors of x and y coordinates
uses the random number generator
