How to judge the importance of predictor variables

Karen Wood


Hi

Question: What SPSS output statistic would you use to judge the importance of a variable?

Background:

Hierarchical regression.

Six predictor variables entered one at a time.

To determine the importance of each variable, I have used the square of the part correlation to determine the unique variance when all sex variables have been entered into the model (last step). Commonality analysis with six variables to determine how much variance is shared between the predictor variables seems a long winded procedure for determining the importance of each variable.

What about beta?

What are others using?
