stelfi 0.0.2

Breaking changes

  • None

New features

  • None

Minor improvements and fixes

  • Bug fix for show_hawkes_GOF(), compensator plotted on goodness of fit plots
  • Additional testthat tests for utility functions meshmetrics(), show_hawkes_GOF(), and get_fields()
  • Additional testthat tests for fitting/simulation functions sim_hawkes(..., method = "2") and sim_lgcp()

stelfi 0.0.1

Initial release

Model fitting functions include

  • fit_hawkes() and fit_hawkes_cbf() to fit self-exciting Hawkes processes to temporal point pattern data
  • fit_lgcp() fits a log-Gaussian Cox process to either spatial or spatiotemporal point pattern data. If a spatiotemporal model is fitted an AR1 process is assumed for the temporal progression
  • fit_mlgcp() fits a joint likelihood model between the point locations and mark(s)
  • fit_stelfi() fits self-exciting spatiotemporal Hawkes models to point pattern data. The self-excitement is Gaussian in space and exponentially decaying over time. In addition, a GMRF can be included to account for latent spatial dependency
