Simulate Matern Model I
Generate a random point pattern, a simulated realisation of the Mat'ern Model I inhibition process model.
Usage
rMaternI(kappa, r, win = owin(c(0,1),c(0,1)))
Arguments
- kappa
- Intensity of the Poisson process of proposal points. A single positive number.
- r
- Inhibition distance.
- win
- Window in which to simulate the pattern.
An object of class
"owin"
or something acceptable toas.owin
.
Details
This algorithm generates a realisation of Mat'ern's Model I
inhibition process
inside the window win
.
The process is constructed by first
generating a uniform Poisson point process of ``proposal'' points
with intensity kappa
inside the window.
A proposal point is deleted if it lies within r
units' distance
of another proposal point. Otherwise it is retained.
The retained points constitute Mat'ern's Model I.
Value
- The simulated point pattern (an object of class
"ppp"
).
