ANCOVA: how to recreate equation based on SPSS output?

I performed an ANCOVA with 3 covariates (Analyze>GLM>Univariate…). I would like to use the output that SPSS provides to calculate the adjusted values for my independent variable for each individual. I am trying to do this by figuring out the equation that SPSS uses to calculate the estimated adjusted means. Any help on how to do this would be greatly appreciated!

What I've done until now: I clicked on the "parameter estimates" options, which provided me with B values for my covariates and the intercept value. The problem is that SPSS is also giving me a B value for all levels of my dependent variable, except for the last variable. It gives me the note: "This parameter is set to zero because it is redundant".

Thanks in advance for any help you may provide,
-H

Fri, 19 Dec 2014 21:11:35 GMTWhen making a linear mixed model what does the repeated variable do? I want to be able to relate what I'm clicking on and the statistics that happen. Conceptually, I understand what a repeated measure is, but what is actually happening when I specify a repeated variable in the "Specify Subjects and Repeated" dialogue? I've seen examples in textbooks and online where there are repeated measures, but they don't specify a repeated variable (i.e. there's no '/REPEATED' statement). It's certainly not a trivial field because in my own analyses, specifying a variable in the "Repeated:" box affects the model. Can someone offer an explanation of how the repeated variable affects the general matrix specification, Yi=Xib+Ziui+e? Does it affect the variance-covariance matrix? Does it change how Yi is indexed?
