Quantlet: | SPPPpsim | |
Description: | Simulates a Binomial (Poisson) spatial point process. Note that SPPPinit or SPPPsetregion must have been called before to set the domain. To be able to reproduce results, reset the random number generator for point processes by calling SPPPinitrandom first. |
Usage: | ppsim = SPPPpsim (nsim, n) | |
Input: | ||
nsim | scalar - number of simulations | |
n | scalar - number of points in the domain | |
Output: | ||
res | list - consisting of components xmat, ymat, type -- | |
xmat | n x nsim - matrix consisting of x coordinates | |
ymat | n x nsim - matrix consisting of y coordinates | |
type | string - "PSIM" |
