Hello everyone,

I am using DPABI statistical analysis to run Mixed-Effect Linear Model.

These are my groups:

G1C1

G1C2

G2C1

G2C2

I’m not sure how to interpret the interaction effect? What does it represent? Is it the group difference in the change? If so, what is the contrast effects (i.e. change in G1 – change in G2?)

Regards,

Winson

## Interaction means the change

Interaction means the change in G1 is different from change in G2. You can refer to some stats books.
