The lower order components ofEV 2 V 5 are the variablesE,V 2 ,V 5 ,EV 2 ,EV 5 ,andV 2 V 5 .Because of the hierarchy principle, i ...

Note that if a model is HWF, then tests for the highest-order terms in the model are always independent of the coding of the var ...

X. An Example We review the guidelines recommended to this point through an example. We consider a car- diovascular disease stud ...

However, we have restricted theVs to theCs themselves primarily because there are a mod- erately large number ofCs being conside ...

According to our strategy, it is necessary that our initial model, or any subsequently deter- mined reduced model, be hierarchic ...

The reason why the model contains all fiveVs at this point is because we have not yet done any analysis to evaluate which of the ...

The computer results for this final model are shown here. This includes the estimated regres- sion coefficients, corresponding s ...
