Sous chaque méthode, ses extensions (Q CS XT Z ZZ IB W U) : en gras et cochée, elle existe ; barrée, elle n'existe pas. Les extensions et leur sens
Aucune méthode de cette classe n'est exécutée sur cette page : la classe touche aux fichiers, au réseau, aux processus, à l'horloge, au hasard ou au son, et un exemple exécuté ici ne serait que l'exemple de ses effets. Chaque méthode porte l'explication que la bibliothèque donne d'elle-même.

Kind
what it ISaucune extension
HasInteraction
DOES THIS PROCESS PLACE POINTS WITHOUT REGARD TO ONE ANOTHER? The three that do are the honest null models -- whatever a statistic sees in their output is chance. The four that do not have an interaction built in, and are what a caller tests FOR.aucune extension
IsClustering
(sans commentaire dans la source : le nom se lit comme une phrase) is clusteringaucune extension
IsInhibiting
(sans commentaire dans la source : le nom se lit comme une phrase) is inhibitingaucune extension
SetIntensity
the parameters, under the names they have in the subject ------------- points per square kilometre -- :Poisson, :MaternIIQCSXTZZZIBWU
Intensity
(sans commentaire dans la source : le nom se lit comme une phrase) intensityaucune extension
SetCount
how many points exactly -- :Binomial, :SSIQCSXTZZZIBWU
SetParentIntensity
clusters per square kilometre -- :MaternCluster, :Thomas. The parents are NEVER DRAWN: they are where the clusters are, not points of the pattern, and a reader who saw them would be looking at a mechanism rather than at data.QCSXTZZZIBWU
SetMeanChildren
(sans commentaire dans la source : le nom se lit comme une phrase) set mean childrenQCSXTZZZIBWU
MeanChildren
(sans commentaire dans la source : le nom se lit comme une phrase) mean childrenaucune extension
SetRadiusKm
the radius of a Matern cluster's disc, kmQCSXTZZZIBWU
SetSigmaKm
the scale of a Thomas cluster's Gaussian, km. It is NOT a radius: about a third of the children land beyond it and a few land far out, which is the whole difference from Matern and is a claim about the mechanism.QCSXTZZZIBWU
SetHardCoreKm
the distance no two points may come within -- :MaternII, :SSIQCSXTZZZIBWU
HardCoreKm
(sans commentaire dans la source : le nom se lit comme une phrase) hard core kmaucune extension
SetIntensityField
THE INTENSITY SURFACE of an inhomogeneous process, as a GE7b field. That is not a workaround for the engine taking no callbacks: a kernel density estimated from one pattern IS such a field, so the natural workflow -- read a population surface, then ask whether the cases are clustered beyond it -- is two calls with nothing in between.QCSXTZZZIBWU

HasIntensityField

ExpectedCount
For the two CLUSTER processes this is the count BEFORE the window clips it. Children thrown outside are lost, and how many depends on how far the mechanism scatters them -- measured on a one-degree square, a Matern cluster of radius 8 km loses 6 per cent and a Thomas of sigma 4 km loses 17, because a Gaussian has no edge. The loss is real and it is the window's, not the process's.aucune extension
GenerateIn
ONE PATTERN FROM THIS PROCESS, inside a window, as a flat lon/lat list.QCSXTZZZIBWU
PatternIn
...and the same as a stzGeoPoints, ready to be measuredaucune extension
EnvelopeOf
THIRTY-NINE IS THE CLASSIC COUNT, and it is not a floor to be raised for free precision: the band WIDENS with the number of simulations, so an envelope of 999 is a stricter test than an envelope of 39 and the two are not comparable. Being the most extreme of forty is a one-in-forty event under the null -- 2.5 per cent on each side. The count belongs in whatever gets reported.QCSXTZZZIBWU
EscapesOf
WHERE AN OBSERVED PATTERN ESCAPES THIS PROCESS'S BAND, and which way: -1 below, 0 inside, +1 above. A reader wants the RANGE OF SCALES at which a pattern is unusual, not one verdict -- a wood can be clustered at ten metres and regular at fifty, and a single p-value cannot say that.aucune extension
VerdictOn
THE VERDICT IN WORDS, with the scales it holds at -- which is the only honest summary, because "clustered" without a range is not a finding.aucune extension
