A collection of minimal Examples from various designs with one or two factors.

Source: R/minimalExamples.R

The datasets present minimal examples that are analyzed with an Analysis of Frequency Data method (described in Laurencelle and Cousineau (2023) . The five datasets are

  • 'minimalBSExample': an example with a single factor (state of residency)

  • 'twoWayExample': an example with two factors, Class and Difficulty

  • 'minimalWSExample': an example with a within-subject design (three measurements)

  • 'twoWayWithinExample': an example with two within-subject factors

  • 'minimalMxExample': a mixed design having one within and one between-subject factors
