Hi there,
I am running a logistic regression and struggling to understand how to state a relative importance of each of the attributes within the model.
I have the 'estimates' (I think this would be the 'b' values in SPSS), but my variables have different scales (some are binary and some are 7 point scales).
How would I move from the 'estimates' to something like a '% contribution' to the model? One thought I had was to use the odds-ratios (and looking at their relative contribution), but do I also need to consider the different scales in this (e.g., by multiplying the odds-ratios but the range of the respective variables)? Or this approach not correct at all?
Any advice would be really appreciated!
Many thanks!
