Hi, all,

 

I'm checking the increase rates of outpatient visits for certain diseases on the same sample. As you see,

The number of outpatient visits all increased after a time point. Among them, Disease1 had the highest increase rates(50%)

 

Is there any way to do a statistical analysis to compare the increase rates of ‘disease1’ 50% to that of 'total diseases' 27%? The sample is non-independent. I appreciate for any suggestion.

If you have the licence to SAS/ETS, you should consider proc countreg to fit your data. Look at the following example:
