Domain Analysis
A DOMAIN statement requests that the procedure perform regression analysis for each domain.
For a domain D, let 
be the corresponding indicator variable:
![\[ I_{D}(h,i,j) = \left\{ \begin{array}{ll} 1 & \mbox{if observation $(h,i,j)$ belongs to domain \Mathtext{D}} \\ 0 & \mbox{otherwise} \end{array} \right. \]](images/statug_surveyreg0114.png){kind=small} |
Let
![\[ v_{hij} = w_{hij}I_ D(h,i,j) = \left\{ \begin{array}{ll} w_{hij} & \mbox{if observation } (h,i,j) \mbox{ belongs to domain } D \\ 0 & \mbox{otherwise} \end{array} \right. \]](images/statug_surveyreg0115.png){kind=small} |
The regression in domain D uses v as the weight variable.
