Hi, I currently analyze my research and I got a problem with decomposition. My experiment design is 2*2*2 mixed ANOVA. Two categorical variables and one continuous variable(which is dependant). TargetColor and Direction is between variable so that I coded 1 and 2. Value is within variable so that I coded as PlusBias and MinusBias with dependent value.
I want to know simple main effects on three way interaction. Here is my data and code. I tried to decompose with LMATRIX. However if I put the within variable into interaction code like Value*Direction interaction at TargetColor1, it doesn't work at all.
Is it impossible to decompose with LMATIRX? or did i do something wrong with spss data code?
Really want to know... Thanks
