plot_moderator_d_linerange {plotBart}

Plot the posterior interval of the Conditional Average Treatment Effect grouped by a discrete variable

Description

Plots the range of the Conditional Average Treatment Effect grouped by a discrete variable. This is analogous to plot_moderator_d_density but is preferable for moderators with many categories. Rather than plotting the full density, the posterior range is shown.

Usage

plot_moderator_d_linerange(.model, moderator, .alpha = 0.7, horizontal = FALSE)

Arguments

.model

a model produced by 'bartCause::bartc()'

moderator

the moderator as a vector

.alpha

transparency value [0, 1]

horizontal

flip the plot horizontal?

Value

ggplot object

 confounders = as.matrix(lalonde[, confounders]),
 estimand = 'ate',
