I can't seem to find a consistent mortality rate formula. Is the one featured on this webpage, http://health.mo.gov/training/epi/CrudeRate.html correct?
(it's Mortality Rate = deaths occuring during a given time period/size of the population which the deaths occurred * 10^n)
Also, I can't find one for attack rate
