Transform Spacetime SPDE Model Parameters to Original Scale
Description
This function takes a vector of transformed parameters and applies the appropriate transformations to return them in the original scale for use in spacetime SPDE models.
Usage
transform_parameters_spacetime(theta, st_model)
Arguments
theta |
A numeric vector containing the transformed parameters in this order:
|
st_model |
A list containing the spacetime model parameters:
|
Value
A named list with the parameters in the original scale:
- kappa
The original scale for kappa (exponential of lkappa).
- sigma
The original scale for sigma (exponential of lsigma).
- gamma
The original scale for gamma (exponential of lgamma).
- rho (optional)
The original scale for rho.
- rho2 (optional)
The original scale for rho2, if d = 2.
