scan - Single-Case Data Analyses for Single and Multiple Baseline Designs

A collection of procedures for analysing, visualising, and managing single-case data. Multiphase and multibaseline designs are supported.

Analysing methods include

• regression models (multilevel, multivariate, bayesian),
• between-case standardized-mean difference,
• overlap indices (including ‘PND’, ‘PEM’, ‘PAND’, ‘NAP’, ‘PET’, ‘IRD’, ‘CDC’),
• Tau-U methods (including meta analysis; baseline corrected tau), and
• randomization tests.

Data preparation functions support outlier detection, handling missing values, scaling, and custom transformations.
An export function helps to generate html, word, and latex tables in a publication friendly style. A shiny app allows to use scan in a graphical userinterface.

More details can be found in the online book ‘Analyzing single-case data with R and scan’, Juergen Wilbert (2026)
