Webb10 apr. 2013 · 4. Interaction terms in Poisson regression models are interpreted as a ratio of ratios of rates. With an interaction term, your model's interpretation of that parameter would be, "a rate ratio comparing condition Y to X among individuals of type 2 relative to rate ratio comparing condition Y to X among individuals of type 1". WebbA partial interaction allows you to apply contrasts to one of the effects in an interaction term. For example, we can draw the interaction of collcat by mealcat like this below. Say that we wanted to compare, in the context of this interaction, group 1 for collcat vs. groups 2 and 3. The table of this partial interaction would look like this.
