ANOVA, N way

Fits an analysis of variance model, displays type I,II,III sum of squares, displays marginal means and contrasts (using marginal means).

In statistics, an N-way ANOVA (Analysis of Variance) with blocks refers to a statistical analysis that involves multiple independent variables or factors (more than two). The term "blocks" in this context refers to a way of handling potential sources of variability that are not the primary focus of the study but need to be accounted for to improve the precision of the analysis.

N-way ANOVA indicates that there are multiple independent variables (factors). For example, in a 2-way ANOVA, there are two independent variables, and in an N-way ANOVA, there are more than two. Each independent variable can have multiple levels or categories.
