One way <strong>to</strong> “think about” path analysis is as a way of “sorting out”<br />
the colinearity patterns amongst the predic<strong>to</strong>rs – asking yourself<br />
what may be the “structure” -- temporal &/or causal relationships -<br />
- among these predic<strong>to</strong>rs that produces the pattern of colinearity.<br />
“Structure” of a MR model – with<br />
hypotheses about which predic<strong>to</strong>rs<br />
will contribute<br />
1<br />
A proposed structure for the colinearity<br />
among the predic<strong>to</strong>rs and how they<br />
relate <strong>to</strong> the criterion – with hypotheses<br />
about which paths will contribute<br />
