plot_SATE {plotBart}

Plot histogram or density of Sample Average Treatment Effects

Description

Plot a histogram or density of the Sample Average Treatment Effect (SATE). The Sample Average Treatment Effect is derived from taking the difference of each individual's observed outcome and a predicted counterfactual outcome from a BART model averaged over the population. The mean of SATE will resemble means of CATE and PATE but will account for the least uncertainty.

Usage

plot_SATE(
  .model,
  type = c("histogram", "density"),
  ci_80 = FALSE,
  ci_95 = FALSE,
  reference = NULL,
  .mean = FALSE,
  .median = FALSE
)

Arguments

.model

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

type

histogram or density

ci_80

TRUE/FALSE. Show the 80% credible interval?

ci_95

TRUE/FALSE. Show the 95% credible interval?

reference

numeric. Show a vertical reference line at this x-axis value

.mean

TRUE/FALSE. Show the mean reference line

.median

TRUE/FALSE. Show the median reference line

Value

ggplot object
