p-value (H0: λy/λx≤1; HA: λy/λx > 1). Assume that Y ∼ Poisson(nλy) and X ∼ Poisson(mλx). n=total population around (< 4 km) Foci; m=total population outside (≥4 km) Foci. Y = Cases around (< 4 km) Foci; X = Cases outside (≥4 km) Foci influence.
Exact confidence interval α=0.05 to the ratio λy/λx.
SIR=Standardize Incidence Ratio by age group with respect to Murcia Region.
Exact Confidence Interval α=0.05.
Lowest number of observed cases which would be statistical significant at the one sided 5% type one level or less test using this test. In brackets: Exact value of the one sided type one error corresponding to this limit.
