Contains definitions and support for linear networks, including creation of networks, geometrical measurements, topological connectivity, geometrical operations such as inserting and deleting vertices, intersecting a network with another object, and interactive editing of networks. Data types defined on a network include point patterns, pixel images, functions, and tessellations. Exploratory methods include kernel estimation of intensity on a network, K-functions and pair correlation functions on a network, simulation envelopes, nearest neighbour distance and empty space distance, relative risk estimation with cross-validated bandwidth selection. Formal hypothesis tests of random pattern (chi-squared, Kolmogorov-Smirnov, Monte Carlo, Diggle-Cressie-Loosmore-Ford, Dao-Genton, two-stage Monte Carlo) and tests for covariate effects (Cox-Berman-Waller-Lawson, Kolmogorov-Smirnov, ANOVA) are also supported. Parametric models can be fitted to point pattern data using the function lppm() similar to glm(). Only Poisson models are implemented so far. Models may involve dependence on covariates and dependence on marks. Models are fitted by maximum likelihood. Fitted point process models can be simulated, automatically. Formal hypothesis tests of a fitted model are supported (likelihood ratio test, analysis of deviance, Monte Carlo tests) along with basic tools for model selection (stepwise(), AIC()) and variable selection (sdr). Tools for validating the fitted model include simulation envelopes, residuals, residual plots and Q-Q plots, leverage and influence diagnostics, partial residuals, and added variable plots. Random point patterns on a network can be generated using a variety of models. authors: - family-names: Baddeley given-names: Adrian email: Adrian.Baddeley@curtin.edu.au orcid: https://orcid.org/0000-0001-9499-8382 - family-names: Turner given-names: Rolf email: rolfturner@posteo.net orcid: https://orcid.org/0000-0001-5521-5218 - family-names: Rubak given-names: Ege email: rubak@math.aau.dk orcid: https://orcid.org/0000-0002-6675-533X - family-names: McSwiggan given-names: Greg preferred-citation: type: book title: 'Spatial Point Patterns: Methodology and Applications with R' authors: - family-names: Baddeley given-names: Adrian email: Adrian.Baddeley@curtin.edu.au orcid: https://orcid.org/0000-0001-9499-8382 - family-names: Rubak given-names: Ege email: rubak@math.aau.dk orcid: https://orcid.org/0000-0002-6675-533X - family-names: Turner given-names: Rolf email: rolfturner@posteo.net orcid: https://orcid.org/0000-0001-5521-5218 year: '2015' publisher: name: Chapman and Hall/CRC Press address: London isbn: '9781482210200' url: https://www.routledge.com/Spatial-Point-Patterns-Methodology-and-Applications-with-R/Baddeley-Rubak-Turner/p/book/9781482210200/ repository: https://spatstat.r-universe.dev repository-code: https://github.com/spatstat/spatstat.linnet commit: e2b240682d90b63353b8982d335d921b787b9a22 url: http://spatstat.org/ date-released: '2024-09-06' contact: - family-names: Baddeley given-names: Adrian email: Adrian.Baddeley@curtin.edu.au orcid: https://orcid.org/0000-0001-9499-8382 references: - type: article title: Hybrids of Gibbs Point Process Models and Their Implementation authors: - family-names: Baddeley given-names: Adrian - family-names: Turner given-names: Rolf - family-names: Mateu given-names: Jorge - family-names: Bevan given-names: Andrew journal: Journal of Statistical Software year: '2013' volume: '55' issue: '11' doi: 10.18637/jss.v055.i11 start: '1' end: '43' - type: article title: 'spatstat: An R Package for Analyzing Spatial Point Patterns' authors: - family-names: Baddeley given-names: Adrian - family-names: Turner given-names: Rolf journal: Journal of Statistical Software year: '2005' volume: '12' issue: '6' doi: 10.18637/jss.v012.i06 start: '1' end: '42'
