LSMeans Effects
Indicate effects by which to construct least squares means (LSMeans) in this field.
Note the following points about LSMeans Effects:
When the experimental design is balanced , LSMeans are the same as simple effect means.
When the experimental design is unbalanced , LSMeans are estimates of effect means that would have been observed if the experimental design had been balanced.
Important : LSMeans Effects must also be listed as Fixed Effects , and all variables comprising them must be listed as Class Variables .
To Specify LSMeans Effects:
*
*
*
To specify interactions between effect, type an asterisk ( * ) between the effects. For example, assuming A and B are listed as Class Variables , typing A B A*B specifies variables A and B , and the interaction between A and B , as effects.
*
A vertical bar ( | ) can be used to create main effects and interactions. For example, typing A|B is the same as typing A B A*B .
