R: Set up COSY correlation structures

cosy {brms} | R Documentation

## Set up COSY correlation structures

### Description

Set up a compounds symmetry (COSY) term in brms. The function does not evaluate its arguments – it exists purely to help set up a model with COSY terms.

### Usage

    cosy(time = NA, gr = NA)

### Arguments

`time` | An optional time variable specifying the time ordering of the observations. By default, the existing order of the observations in the data is used.
`gr` | An optional grouping variable. If specified, the correlation structure is assumed to apply only to observations within the same grouping level.

### Value

An object of class `'cosy_term'`, which is a list of arguments to be interpreted by the formula parsing functions of brms.

### See Also

`autocor-terms`

### Examples

    data("lh")
    lh <- as.data.frame(lh)
    fit <- brm(x ~ cosy(), data = lh)
    summary(fit)
