Set up COSY correlation structures
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.
cosy(time = NA, gr = NA)
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. |
An object of class 'cosy_term', which is a list
of arguments to be interpreted by the formula
parsing functions of brms.
