## Function Anova-Two-Way-Variables

(

**anova-two-way-variables** &rest < args > )

anova-two-way-variables (dv iv1 iv2)

Calculates the analysis of variance when there are two factors that may

affect the dependent variable, specifically ` iv1' and `

iv2.' Unlike the one-way

ANOVA, there are mathematical difficulties with the two-way ANOVA if there are

unequal cell sizes; therefore, we require all cells to be the same size; that

is, the same number of values (of the dependent variable) for each combination

of the independent factors.

The result of the analysis is an anova-table, as described in the manual. This

function differs from ` anova-two-way-groups' only in its input representation.<br> See the manual for further discussion of analysis of variance. <br> The row effect is `

iv1' and the column effect is `iv2.'
