R: (Deprecated) Fixed user-defined covariance matrices

cor_fixed {brms} | R Documentation

## (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)

### 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 `cor_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 = cor_fixed(V))

    ## End(Not run)
