The Parameters for the Fixed Effects Model with Interaction Are $\alpha _ { i } = \mu _ { i } - \mu , \beta _ { j } = \mu _ { j } - \mu,$

Short Answer

The parameters for the fixed effects model with interaction are $\alpha _ { i } = \mu _ { i } - \mu , \beta _ { j } = \mu _ { j } - \mu,$ and $\gamma _ {y} = \mu _ { y } - \left( \mu + \alpha _ { i } + \beta _ { j } \right)$ Thus the model is $\mu _ { y } = \mu + \alpha _ { i } + \beta _ { j } + \gamma _ { y }$ The $\alpha _ {i } ^ { \prime } s$ are called the __________ for factor A, whereas the $\beta _ { j } ^ { \prime } s$ are the __________ for factor B. The $\gamma _ { 4 } ^ { \prime } s$ are referred to as the __________ parameters.
