Covariance and Correlation Matrix of Population-Level Effects
Description
Get a point estimate of the covariance or correlation matrix of population-level parameters
Usage
## S3 method for class 'brmsfit'
vcov(object, correlation = FALSE, pars = NULL, ...)
Arguments
object |
An object of class |
correlation |
Logical; if |
pars |
Optional names of coefficients to extract. By default, all coefficients are extracted. |
... |
Currently ignored. |
Details
Estimates are obtained by calculating the maximum likelihood covariances (correlations) of the posterior draws.
Value
covariance or correlation matrix of population-level parameters
Examples
## Not run:
fit <- brm(count ~ zAge + zBase * Trt + (1+Trt|visit),
data = epilepsy, family = gaussian(), chains = 2)
