Hy,

I raise an unresolved issue posted in 2013.

I am wondering if anyone has had experience working with indirectly standardized rates.

Standardized rates is the product of the target crude rate and the ratio of observed to expected values from the relevant regression model.

In short, I try to compute the control limits by using the formulas in Appendix A.2.1.in Spiegelhalter's 2005 paper on funnel plots.

I'm working on SAS 9.3.

Thanks,

IE

Hi:

Look at these 2 blog posts. One of them mentions the Spiegelhalter paper:

Thank you for answering.

These papers are for binomial and normal variables, I'm looking for the application for poisson variable.

I try to.It seems to work for smr (target theta=1) but for standardized ratio with target not equal to 1, it is not so simple.

Thank you anyway.

Hi Isevr,

I am having the same problem as you. Did you manage to write a sytnax for the intervals for SMR using the poisson distribution? Would you mind sharing it? That would be so helpful!

Thanks a lot!
