transreg (version 1.0.5)

weights.transreg: Extract Weights

Description

Extracts weights from an object of class [transreg].

Usage

# S3 method for transreg
weights(object, stack = NULL, ...)

Value

Returns weights. The output is a numerical vector with one entry for each source of co-data.

Arguments

object

object of class `transreg`

stack

character "sta" (standard stacking) or "sim" (simultaneous stacking)

...

This function is about weights for sources of prior effects. To extract weights for features (estimated regression coefficients), use [coef()].

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)
weights(object)
