Dear listers,
I´ve got the incidence of a disease in a population in the following data format -year,population,cases-
I´ve created the incidence rate by dividing cases by population and multiplying by 100000.
gen ins=(cases/population)*100000
poisson cases year population
**no tendency for increasing incidense after correcting for population.
**however
line ins ye
**shows an increasing trend. But I´d like to add 95% CI lines to corroborate this. Is this at all possible given my dataset??
Regards,
//M
