Re: st: calculating SMRs, examples?
Are there any good websites or books out there that explain in detail
how to calculate a standardized mortality ratio (SMR) with poisson
regression using external rates? I find that the STATA manuals do not
contain a lot of information regarding this topic, any suggestions?
I wrote, among other things:
You may proceed from here to -poisson-; it requires the expected number
. gen edeaths = pyrs*mrate
. poisson _d exposure(edeaths) , irr
- and that was wrong. The -poisson- command should be:
. poisson _d , exposure(edeaths)
To obtain the SMR, use -lincom- after -poisson-:
. lincom _cons , irr
I hope this was not too confusing.
