Then the main and the interaction models for estimating the average or mean value for the variable y is shown below: Main Effects Model with Two qualitative Independent Variables, One at Three Levels (F, F, F, ) and the other at Two Levels (B, ,%) where Ax, +A+, s the main effect term for F and A,xs is the main effect for B 2 (If F, is base level) 0 if not f Fis base level) 20 if not (Base level) Interpretation of model parameters = " (Mean of the combination of base levels) = ',-Ar for any level B, (j = 1,2) =3,- 'for any level B,U-12) .-M1-Av for any level F: (i=1,2,3) lype here to searchExplanation / Answer
In every case of plotting data involving dependent and one or more independent variables , the vertical axis (or the Y axis) represents the dependent variable, and the horizontal axis (or the X axis) represent an independent (or classification) variable.
If you have two independent variables (including classification variables), one will be plotted on the horizontal axis. The other will be represented by plotting multiple lines on the graph. A third independent or classification variable can be plotted by using additional lines, or by drawing multiple graphs side by side.The type of graph that is obtained depends on whether or not there are interactions or main effects.
The graph may be shown to have parallel lines because of one of the following reasons:
