The PROPOR extension command provides binomial and Poisson CIs.  It can take aggregate counts in the dialog or pass the data in syntax.

It requires the Python Essentials.  Both the Essentials and the command can be downloaded via the SPSS Community website (www.ibm.com/developerworks/spssdevcentral).

Hello,

Per my title, is there a way to calculate a 95% CI for a proportion that is
close to 0 (0.1% to be more specific)? There are plenty of online
calculators but I was hoping to avoid calculating manually. I am using IBM
SPSS 19.
Thank you!
