comparing b weights across groups

[Matthew Fuller-Tyszkiewicz]

Hello all.

I have conducted a multiple regression with job satisfaction as the DV and a variety of personality traits as the IVs. All variables are continuous. I have conducted this multiple regression separately across different groups and now wish to compare the importance of individual IVs across groups.

I understand that Fisher's Z conversion is useful for comparing bivariate correlations and even for comparing R values in multiple regression. Is this method also suitable for use with beta weights?

Thanks in advance for your help,
Matt

PS: reference material on this issue would be greatly appreciated.

If you include the grouping variable and the interaction of the grouping
variable with each predictor in addition to the predictor variable
alone, the interaction provides a test of the equality of slopes across
groups.

Hello all.

I have conducted a multiple regression with job satisfaction as the DV
and a variety of personality traits as the IVs. All variables are
continuous. I have conducted this multiple regression separately across
different groups and now wish to compare the importance of individual
IVs across groups.
