ggplot.posterior_diff: Visualize the Posterior Distributions of Model Differences

Description

A density is created for each contrast in a facetted grid.

Usage

# S3 method for posterior_diff

  environment = NULL, size = 0)

Arguments

data

An object produced by contrast_models().

mapping, ..., environment

Not currently used.

size

The size of an effective difference. For example, a 5% increase in accuracy between two models might be considered a "real" difference.

Value

A ggplot2::ggplot() object using geom_density facetted by the models being contrasted (when there are 2 or more contrasts).
