cor_fixed: (Deprecated) Fixed user-defined covariance matrices

Description

This function is deprecated. Please see fcor for the new syntax. Define a fixed covariance matrix of the response variable for instance to model multivariate effect sizes in meta-analysis.

Usage

cor_fixed(V)

Value

An object of class cor_fixed.

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.

Examples

if (FALSE) {
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 = cor_fixed(V))
}
