Advanced Analysis - Dummy Factors:

Try this example only when you become comfortable with MetaCause Analysis. One or more dummy factors are introduced in addition to a factor if its scatter diagram can be divided into groups/clusters in more than one way. One dummy factor is introduced to represent each additional division of the scatter diagram. Note that in this example values for response cold shuts are discrete (Yes/No).

Note that Main Effects Report account for interactions among all responses and quantify the influence of each factor on each response. Interactions report account for interactions among all factors by taking into account interactions among all responses and quantify factor interactions in pairs for each response. You need to take account of these assumptions while interpreting the effect of dummy factors in MetaCause Reports.

Main Effect Reports assume interactions among all responses. Hence, you must not introduce dummy responses (similar to dummy factors) in MetaCause analysis.
