The original data used to create this object. Can be a
statistical model or such.
stack
Logical, if TRUE, densities are plotted as stacked lines.
Else, densities are plotted for each parameter among each other.
show_intercept
Logical, if TRUE, the intercept-parameter is included
in the plot. By default, it is hidden because in many cases the intercept-parameter
has a posterior distribution on a very different location, so density curves of
posterior distributions for other parameters are hardly visible.
n_columns
For models with multiple components (like fixed and random, count and zero-inflated), defines the number of columns for the panel-layout. If NULL, a single, integrated plot is shown.
