R Commander – two-way analysis of variance

June 25, 2010

Two way analysis of variance models can be fitted to data using the R Commander GUI. The general approach is similar to fitting the other types of model in R Commander described in previous posts.

The “Statistics” menu provides access to some analysis of variance models via the “Means” sub-menu:

  • Multi-way ANOVA – the simplest two-way analysis of variance model that can be applied to a set of data.

The “Models” menu provides access to various diagnostics for analysis of variance models via the “Graphs” sub-menu including:

  • Basic diagnostic plots – four commonly used residual diagnostics including fitted values versus residuals and a normal probability plot for the residuals.

Other useful resources are provided on the Supplementary Material page.
