    Hi All,

    I seen over the web on numerous methodologies to calculate relative
    importance of predictors in a model.
    Some of them

    - Johnsons Relative Importance
    - Kruskal's/Theils
    - Dominance Analysis

    I wonder which one of these is the most preferred and accurate methods
    and how wwe could use them in SPSS.
    Your sincere comments will be fo great help.

    Many Thanks.

    How timely! I find myself asking the exact same question. I am specifically searching the web for "how to" informaton on Johnson's Relative Importance Method as I have been recommended to use this in my dissertation. I haven't finished looking yet, so if I find the answers, I'll try to come back and post. Please do the same!

    That has a good summary by Ray, concerning many of
    the problems.

    It does not mention, explicitly, the problems created by
    the presence of "suppressor variables" - whether or not
    they do deserve to be in any equation (in versus out
    create different logical problems). Or, the notion that
    the correlations, etc., in an equation inevitably limit
    you to statements about the *measured* variable, and
    not about the underlying theoretical construct - When is
    it appropriate to correct for "attenuation" from errors
    of measurement?

    Hi - I am trying to figure out the correlation matrix syntax coding In spss to run relative weights analysis but the jlebreto link isn’t working. Does anyone have an updated link or can send me spss syntax for this analysis? Thanks!
