Extract the group-level ('random') effects of each level
from a brmsfit
object.
## S3 method for class 'brmsfit' ranef( object, summary = TRUE, robust = FALSE, probs = c(0.025, 0.975), pars = NULL, groups = NULL, ... )
object |
An object of class |
summary |
Should summary statistics be returned
instead of the raw values? Default is |
robust |
If |
probs |
The percentiles to be computed by the |
pars |
Optional names of coefficients to extract. By default, all coefficients are extracted. |
groups |
Optional names of grouping variables for which to extract effects. |
... |
Currently ignored. |
A list of 3D arrays (one per grouping factor).
If summary
is TRUE
,
the 1st dimension contains the factor levels,
the 2nd dimension contains the summary statistics
(see posterior_summary
), and
the 3rd dimension contains the group-level effects.
If summary
is FALSE
, the 1st dimension contains
the posterior draws, the 2nd dimension contains the factor levels,
and the 3rd dimension contains the group-level effects.
