EstimatedPointProcess
EstimatedPointProcess[pdata,pproc]
estimates the parametric point process pproc from point data pdata.
EstimatedPointProcess[pdata,pproc,{{p,p0},{q,q0},…}]
estimates the parameters p, q, … with starting values p0, q0, ….
Details and Options
![](Files/EstimatedPointProcess.en/details_1.png)
- EstimatedPointProcess takes point data pdata and returns the symbolic point process pproc with parameter estimates inserted for any non-numeric values.
-
- In general, a process pproc can be better estimated from an ensemble of point data.
-
- 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 - The points are converted to a SpatialPointData object and a Ripley–Rasson estimator is used to generate the observation region if it is not provided in pdata.
- The following options can be given:
-
AccuracyGoal Automatic the accuracy sought PointProcessEstimator Automatic what process parameter estimator to use PrecisionGoal Automatic the precision sought WorkingPrecision Automatic the precision used in internal computations - Settings for PointProcessEstimator are documented under the individual point process reference pages.
