MeanPointDensity

MeanPointDensity[pdata]

estimates the mean point density from point data pdata in the observation region reg.

MeanPointDensity[bdata]

estimates the mean point density from binned data bdata.

MeanPointDensity[pproc]

computes the mean point density for point process pproc.

Details and Options

  • MeanPointDensity is also known as intensity or mean intensity.
  • The mean point density is the average number of points per unit measure of the observation region. It is given by , where is the number of points and is the measure of the observation region reg.
  • The points pdata can have the following forms:
  • {p1,p2,…}points pi
    GeoPosition[…],GeoPositionXYZ[…],…geographic points
    SpatialPointData[…]spatial point collection
    {pts,reg}point collection pts and observation region reg
  • If the observation region reg is not given, a region is automatically computed using RipleyRassonRegion.
  • The point process pproc can have the following forms:
  • proca point process proc
    {proc,reg}a point process proc and observation region reg
  • The observation region reg should be a parameter-free, full-dimensional and bounded region as tested by SpatialObservationRegionQ.
  • The binned data bdata is taken to come from SpatialBinnedPointData.
  • With a point process pproc, either exact formulas or approximate computation methods are used.
