<> Dear Michael, tanks a lot for your help. I guessed as much. Joerg <http://www.dict.cc/englisch-deutsch/I.html> Am 27.09.2010 09:21, schrieb Michael N. Mitchell:

Greetings JoergIf you were doing an OLS regression, I would say that you couldreport the partial (or semi-partial) correlation associated with eachof the variables. However, as you note, you are using binary logisticregression. While you could technically create z scores for the binaryvariables to try and put them on the same scale as the z-transformedvariables, those results would not make much sense. You could take thez-transformed variables and convert them into 0/1 variables by cuttingthem into two arbitrary groups, but that would not make much sense. Mythoughts are that there is not much you can do to compare the "apples"and "oranges" here in terms of the effect size.Best regards, Michael N.

I want to calculate an binarylogistic regression. Ihave all metric variables z-transformed (mean = 0, std=1) to comparethe effect sizebetween the independent variable. But I have also dummys in myRegressionmodell. What cani do to compare the effect size of the dummy's with the effect sizeof the metricindependent variables? Or is that completely impossible?
