adaptive intensity estimation for temporal point patterns using Voronoi-Dirichlet tessellation.
## S3 method for class 'tpp' densityVoronoi(X, f = 1, nrep = 1,at=c("points","pixels"), dimt=128,...)
X |
an object of class |
f |
fraction (between 0 and 1 inclusive) of the data points that will be used to build a tessellation for the intensity estimate |
nrep |
number of independent repetitions of the randomised procedure |
at |
string specifying whether to return the intensity values at a grid of pixel locations and time (at="pixels") or only at the points of X (at="points"). default is to estimate the intensity at pixels |
dimt |
the number of equally spaced points at which the temporal density is to be estimated. see density |
... |
arguments passed to |
This function computes intensity estimates for temporal point patterns using Voronoi-Dirichlet tessellation.
If at="points"
: a vector of intensity values at the data points of X.
If at="pixels"
: a vector of intensity values over a grid.
