What is interaction system?
An interaction system can be seen as a definition of the way systems interact to achieve some common functional goal. A typical example of such a common goal is to allow the end-to-end communication between a large number of (geographically spread) users in a distributed system for different application purposes.
When to use an interaction term in a model?
The most important rule to remember is that when an interaction term is in a model, the main effects are only the expected effects when the other variable involved in the interaction is zero.
How are interactions interpreted in a regression model?
Adding an interaction term to a model drastically changes the interpretation of all the coefficients. If there were no interaction term, B1 would be interpreted as the unique effect of Bacteria on Height. But the interaction means that the effect of Bacteria on Height is different for different values of Sun.
Why are estimates of main effects the same with or without interaction term?
Our second observation above was that the estimates of main effects are the same with/without interaction term when centering the predictor variables. This is because in the models without interaction term (centered or uncentered predictors) the interpretation of β1 is the same as in the model with interaction term and centered predictors.
When to add interaction terms in an ANOVA?
In an ANOVA, adding interaction terms still leaves the main effects as main effects. That is, as long as the data are balanced, the main effects and the interactions are independent. The main effect is still telling you if there is an overall effect of that variable after accounting for other variables in the model.
