precision.intrinsicCBrSPDEobj {rSPDE} | R Documentation |
Get the precision matrix of intrinsicCBrSPDEobj objects
Description
Function to get the precision matrix of a intrinsicCBrSPDEobj object
Usage
## S3 method for class 'intrinsicCBrSPDEobj'
precision(
object,
kappa = NULL,
tau = NULL,
alpha = NULL,
beta = NULL,
ld = FALSE,
...
)
Arguments
object |
The model object computed using |
kappa |
If non-null, update the range parameter. |
tau |
If non-null, update the precision parameter. |
alpha |
If non-null, update the alpha parameter. |
beta |
If non-null, update the beta parameter. |
ld |
If TRUE, return the log determinant of the precision matrix instead of the precision matrix. By default FALSE. |
... |
Currently not used. |
Value
The precision matrix.
