factorMerger: Tools to Support Results from Post Hoc Testing

ANOVA-like statistical tests for differences among groups are available for almost a hundred years. But for large number of groups the results from commonly used post-hoc tests are often hard to in terpret.

To deal with this problem, the factorMerger package constructs and plots the hierarchical relation among compared groups.

Such hierarchical structure is derived based on the Likelihood Ratio Test and is presented with the Merging Paths Plots created with the ggplot2 package.

The current implementation handles one-dimensional and multi-dimensional Gaussian models as well as binomial and survival models. This article presents the theory and examples for a single-factor use cases.
