WebbTwo-way ANOVA You can include multiple explanatory variables with the anova command, and you can specify interactions by placing ‘#’ between the variable names. For instance, typing anova y a b performs a two-way layout of y on a and b. Typing anova y a b a#b performs a full two-way factorial layout. The shorthand anova y a##b does the same. Webb3 Answers.
