Dear all,
I've calcuted incidence rates (using Poisson with offset[logtime] and 1-year age bands and predicitive margins) at four different time points.
Now, I would like to test for trends over time. My plan was to use the JointPoint software, so I created a dataset with all the incidence rates, SE and 95%CI by year, sex, race and age groups. But I can't figure out how to format the dataset to be used in JointPoint - even after downloading two additional softwares (SEERSTAT SEERPREP).
Would anyone in here know how to export data from Stata such that I can run the test in JointPoint?

Kind regards
Jannie
