The purpose of the SMR procedure
is to estimate the confidence interval for
a rate ratio. In practice, this will often
be the Standardized Mortality Ratio, the
Standardized Morbidity Ratio (SMR) or the
Comparative Mortality Figure (CMF). The
rate ratio is most suited to study events
in a constant domain while the denominator
-i.e. the population at risk- is very large.
Including errors in estimate, exact and
fieller analysis.
