cov_fixed: Fixed user-defined covariance matrices

Description

Define a fixed covariance matrix of the response variable for instance to model multivariate effect sizes in meta-analysis.

Usage

cov_fixed(V)

Arguments

V

Known covariance matrix of the response variable. If a vector is passed, it will be used as diagonal entries (variances) and covariances will be set to zero.

Value

An object of class cov_fixed.

Examples

## Not run: 
# dat <- data.frame(y = rnorm(3))
# V <- cbind(c(0.5, 0.3, 0.2), c(0.3, 1, 0.1), c(0.2, 0.1, 0.2))
# fit <- brm(y~1, data = dat, autocor = cov_fixed(V))
# ## End(Not run)
