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,
