lgcp (version 1.8)

lgcpForecast: lgcpForecast function

Description

Function to produce forecasts for the mean field \(Y\) at times beyond the last time point in the analysis (given by the argument T in the function lgcpPredict).

Usage

lgcpForecast(
  lg,
  ptimes,
  spatial.intensity,
  temporal.intensity,
  inclusion = "touching"
)

Arguments

lg

an object of class lgcpPredict

ptimes

vector of time points for prediction. Must start strictly after last inferred time point.

spatial.intensity

the fixed spatial component: an object of that can be coerced to one of class spatialAtRisk

temporal.intensity

the fixed temporal component: either a numeric vector, or a function that can be coerced into an object of class temporalAtRisk

inclusion

criterion for cells being included into observation window. Either 'touching' or 'centroid'. The former includes all cells that touch the observation window, the latter includes all cells whose centroids are inside the observation window.

Value

forcasted relative risk, Poisson intensities and Y values over grid, together with approximate variance.
