dabestr is a package for Data Analysis using Bootstrap-Coupled ESTimation.

Estimation statistics is a simple framework that avoids the pitfalls of significance testing. It uses familiar statistical concepts: means, mean differences, and error bars. More importantly, it focuses on the effect size of one’s experiment/intervention, as opposed to a false dichotomy engendered by P values.

An estimation plot has two key features.

  1. It presents all datapoints as a swarmplot, which orders each point to display the underlying distribution.

  2. It presents the effect size as a bootstrap 95% confidence interval on a separate but aligned axes.

DABEST powers estimationstats.com, allowing everyone access to high-quality estimation plots.

Installation

# Install it from CRAN
install.packages("dabestr")

# Or the development version from GitHub:
# install.packages("devtools")
devtools::install_github(repo = "ACCLAB/dabestr", ref = "dev")

Usage

library(dabestr)

data("non_proportional_data")

dabest_obj.mean_diff <- load(
  data = non_proportional_data,
  x = Group,
  y = Measurement,
  idx = c("Control 1", "Test 1")
) %>%
  mean_diff()

dabest_plot(dabest_obj.mean_diff, TRUE)
