Hi again,

I studied with influence measures of logistic regression of some data by
using R and SPSS and I get different values of DFFITS and Cook's Distance
from SPSS and R outpus, but the coefficients, model formulas and leverage
values are the same.  
Can anyone help me about ; Which is the true or Why this difference occurs ?

Any help will be appricated. Thanks.
