Probably a very basic question, but I have a contingency table formed of 3 categorical variables (one with 3 levels, the rest with 2) and have been asked to try to test the association between them using log-linear modelling. However, the output I get states that residuals are all zero, and remain so regardless of what I specify as the model (e.g. saturated, or just the one variable, or an interaction etc.). I know from other analyses that there is not a perfect relationship between these variables.
What does this mean in terms of the model? Is it an indication that it violates assumptions?
Edited to add the output table:
This is for a model containing the interaction term (which is what we're interested in).
