target.and.grad.SpatioTemporalPlusPars: target.and.grad.SpatioTemporalPlusPars function

In bentaylor1/lgcp: Log-Gaussian Cox Process

Description

A function to compute the target and gradient for the Bayesian spatiotemporal LGCP.

Usage

target.and.grad.SpatioTemporalPlusPars(GP, prior, Z, Zt, eta, beta, nis,
  cellarea, spatial, gradtrunc, ETA0, tdiff)

Arguments

GP	an object created using the stGPrealisation function
prior	the priors for hte model, created using lgcpPrior
Z	the design matrix on the FFT grid
Zt	the transpose of the design matrix
eta	the paramers eta
beta	the parameters beta
nis	the cell counts on the FFT grid
cellarea	the cell area
spatial	the poisson offset
gradtrunc	the gradient truncation parameter
ETA0	the initial value of eta
tdiff	vector of time differences between time points

Value

the target and gradient for the spatiotemporal model.
