Hi dear all,

I'm wondering about the question that; Does the influence.measures(model)
for linear models valid for general linear models such as logistic
regression models?

That is;

If I fit the model like

model <- glm( y~X1+X2, family=binomial)

Then, if  i apply the function "influence.measures(model), i will get the
result of influence measures. 

These result are valid for logistic regression model?

Thanks any help..

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.
