Extract Weights
Description
Extracts weights from an object of class [transreg].
Usage
## S3 method for class 'transreg'
weights(object, stack = NULL, ...)
Arguments
object |
object of class 'transreg' |
stack |
character "sta" (standard stacking) or "sim" (simultaneous stacking) |
... |
(not applicable) |
Value
Returns weights. The output is a numerical vector with one entry for each source of co-data.

Examples
#--- simulation ---
set.seed(1)
n <- 100; p <- 500
X <- matrix(rnorm(n=n*p),nrow=n,ncol=p)
beta <- rnorm(p)
prior <- cbind(beta+rnorm(p),beta+rnorm(p),rnorm(p),rnorm(p))
y <- X %*% beta
#--- example ---
object <- transreg(y=y,X=X,prior=prior)
