It would be necessary to have more detail so that list members can try to help.

You say you are fitting a model.  Are you asking how to fit a model?

What is the model for? Do you want to gain more understanding of churning or are you just interested in developing a model to predict future cases?

What is your definition of churning?  Are you stuck with such a coarse measurement of your DV?

What is a case in your data?  How did you select the cases? How many do you have?

Are all of your predictors continuous?

What is the context? Is this homework? Part of a job? etc.

It seems that the churn rate would simply be the proportion of cases that had churn.  Please explain. 

Google incidence vs prevalence.  Which are you interested in?

Hi All,

I had a query in fitting a model where we are interested in finding the churn rate.

I am fitting a model with DV as Churn (yes/no) and IV as age , tenure, income and etc.

But now we need to weight each IV separately and fit a model........I don know how to do this using spss, I hope anyone will help me to solve this.........thanks in advance.this will be helpful to my career.
