Compare slope values of different brms models

compare_slopes(..., Slope)

Arguments

...: brms models to be compared
Slope: A string containing the name of the covariate to have the slopes compared between models

Value

Returns a table of values with the log(slope model 1/slope model 2)

Examples

if (FALSE) { # \dontrun{

md = dplyr::starwars

# Centering variables
md = md %>% 
  dplyr::select(mass, sex, height, species) %>%

                      "female" = -1, 
                      "hermaphroditic" = 0,
                      "none" = as.numeric(NA)))
