vcov.brmsfit: 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 brmsfit
vcov(object, correlation = FALSE, ...)

Arguments

object

An object of class brmsfit

correlation

logical; if FALSE (the default), compute the covariance matrix, if TRUE, compute the correlation matrix

...

Currently ignored

Value

covariance or correlation matrix of population-level parameters

Details

Estimates are obtained by calculating the maximum likelihood covariances (correlations) of the posterior samples.

Examples

# NOT RUN {
fit <- brm(count ~ log_Age_c + log_Base4_c * Trt_c + (1+Trt_c|visit), 
           data = epilepsy, family = gaussian(), chains = 2)
vcov(fit)
# }
# NOT RUN {
# }
