coef.brmcoda function

Model Coefficients

Extract model coefficients, which are the sum of population-level effects and corresponding group-level effects of the brmsfit object in a brmcoda object.

## S3 method for class 'brmcoda'
coef(object, ...)

Arguments

• object: An object of class brmcoda.
• ...: Further arguments passed to coef.brmsfit.

Returns

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.

Examples

## fit a model
if(requireNamespace("cmdstanr")){
  m <- brmcoda(complr = complr(data = mcompd, sbp = sbp,
                               parts = c("TST", "WAKE", "MVPA", "LPA", "SB"),
                               idvar = "ID", total = 1440),
  formula = Stress ~ bilr1 + bilr2 + bilr3 + bilr4 +
    wilr1 + wilr2 + wilr3 + wilr4 + (1 | ID),
  chain = 1, iter = 500,
  backend = "cmdstanr")
  
  ## extract population and group-level coefficients separately
  fixef(m)
  ranef(m)
  
  ## extract combined coefficients
  coef(m)
