PointProcessFitTest[pdata]
tests whether the point collection pdata could be modeled by a Poisson point process.
PointProcessFitTest[pdata,pproc]
tests whether the point collection could be modeled by the point process pproc.
Details and OptionsUniform point distribution on a disk:
The data came from a point process with homogeneous intensity:
Points distributed over a geographical region:
Estimated PoissonPointProcess:
Scope (10) Testing (7)The -values are typically large when points are uniformly distributed:
The -values are typically small when there is spatial heterogeneity:
Perform a particular test for spatial randomness:
Using Automatic applies the "BesagL" test:
The property "AutomaticTest" can be used to determine which test was chosen:
Perform all tests appropriate to the data simultaneously:
Use the property "AllTests" to see which tests are available:
Create a HypothesisTestData object for repeated property extraction:
The properties available for extraction:
Extract some properties from the HypothesisTestData object:
The -value and test statistic from the "BesagL" test:
Extract any number of properties simultaneously:
The -value and test statistic from a "BesagL" test:
Reporting (3)Tabulate the results from a selection of tests:
A full table of all appropriate test results:
A table of selected test results:
Retrieve the entries from a test table for customized reporting:
The -values are above 0.05, so there is not enough evidence to reject at that level:
Tabulate -values for a test or group of tests:
A table of -values from all appropriate tests:
Options (2) SignificanceLevel (1)The significance level is used for "TestConclusion" and "ShortTestConclusion":
The test conclusions may differ:
MaxIterations (1)You can control the number of simulations with suboption MaxIterations:
