gev.update.lambda: Update the lambda parameter in a Gaussian Process
Description
This constructs a focused proposal to make a metropolis-hasting update
of the lambda parameter in a Gaussian process. It is agnostic to
which model component in the spatial GEV the GP belongs to.
Usage
gev.update.lambda(tau, alpha, lambda, D, a, b)
Arguments
tau
A vector of the random effects
alpha
The global precision of the Gaussian process
lambda
The current value of lambda
D
The matrix of distances between the points associated with the
vector tau
a
The parameter for the prior of lambda
b
The second parameter for the prior of lambda
Value
A scalar which is the updated value of lambda.
