spT.priors: Priors for the spatio-temporal models.

In spTimer: Spatio-Temporal Bayesian Modelling

Priors for the spatio-temporal models.

Description

This command is useful to assign the hyper-parameters of the prior distributions.

Usage

spT.priors(model="GP", inv.var.prior=Gamm(a=2,b=1),
  beta.prior=Norm(0,10^10), rho.prior=Norm(0,10^10))

Arguments

model	The spatio-temporal models, current input: "GP", "AR", and "GPP".
inv.var.prior	The hyper-parameter for the Gamma prior distribution (with mean = a/b) of the precision (inverse variance) model parameters (e.g., 1/\sigma2_\epsilon, 1/\sigma2_\eta).
beta.prior	The hyper-parameter for the Normal prior distribution of the \beta model parameters.
rho.prior	The hyper-parameter for the Normal prior distribution of the \rho model parameter.

Note

If no prior information are given (assigned as NULL), then it use flat prior values of the corresponding distributions.
Gamm and Norm refers to Gamma and Normal distributions respectively.
