Domain Analysis
A DOMAIN statement requests that the procedure perform logistic regression analysis for each domain.
For a domain 
, let 
be the corresponding indicator variable:
![\[ I_{\Omega }(h,i,j) = \left\{ \begin{array}{ll} 1 & \mbox{if observation }(h,i,j)\mbox{ belongs to }\Omega \\ 0 & \mbox{otherwise} \end{array} \right. \]](images/statug_surveylogistic0255.png)
Let
![\[ v_{hij} = w_{hij}I_\Omega (h,i,j) = \left\{ \begin{array}{ll} w_{hij} & \mbox{if observation } (h,i,j) \mbox{ belongs to } \Omega \\ 0 & \mbox{otherwise} \end{array} \right. \]](images/statug_surveylogistic0256.png)
The regression in domain uses v as the weight variable.
