spTimer (version 0.02)

spT.decay: Choice for sampling spatial decay parameter $\phi$.

Description

This function initialises the sampling method for the spatial decay parameter $\phi$.

Usage

spT.decay(type="MH", tuning=NULL, limit=NULL, segments=NULL, value=NULL)

Arguments

type

The sampling method, currently available methods are, DISCRETE and MH. One can also used FIXED value for $\phi$ parameter.

tuning

If MH type is used then need to define the tuning parameter for $\phi$.

limit

If DISCRETE type is used then need to define the lower and upper limits.

segments

If DISCRETE type is used then need to define the number of segments for the range of limits.

value

If FIXED type is used then need to define the value for $\phi$.

Examples

## 

# input for random-walk Metropolis within Gibbs 
# sampling for phi parameter
spatial.decay<-spT.decay(type="MH", tuning=0.08)

# input for discrete sampling of phi parameter
spatial.decay<-spT.decay(type="DISCRETE",
           limit=c(0.01,0.02),segments=5)

# input for spatial decay if FIXED is used
spatial.decay<-spT.decay(type="FIXED", value=0.01)
