Simple exact analysis of the standardised mortality ratio
The standardised mortality ratio is the ratio of deaths observed, D, to those expected, E, on the basis of the mortality rates of some reference population. On the usual assumptions--that D was generated by a Poisson process and that E is based on such large numbers that it can be taken as without error--the long established, but apparently little known, link between the Poisson and chi 2 distributions provides both an exact test of significance …
Simplified exact analysis of case-referent studies: Matched pairs; dichotomous exposure
In a case-referent study of matched pairs with a single dichotomous exposure variable, the relative risk R is estimated from the "discordant pairs," r and s, by R = r/s. In this paper the exact (1 - alpha) confidence limits, RL and RU, have been simplified, and a new exact test of the null hypothesis that R = 1 has been derived. The exact methods depend on the F distribution; they are simple to calculate and all have been fully validated. Even af…
Motor vehicle accidents (1973-6) in a cohort of Montreal drivers
In 1973-4 nearly 10 000 Montreal drivers, interviewed by telephone, provided information about medical and associated factors and about driving habits, in particular annual mileage. Records of accidents suffered by these drivers in the Province of Quebec over 39 months (1973-6) were also collected. The 7634 current drivers, with appropriate permits, and all of whose data passed reliability edits, were placed into nine sets-that is, three classes:…
