TL;DR
It is shown how one can compute the power of the test and how the principle of the comparison is recalled i.e. computation of the standardised mortality radio and test of the null hypothesis.
Abstract
This note derives the power of the test comparing the mortality of a cohort to the mortality of a reference population. The principle of the comparison is recalled i.e. computation of the standardised mortality radio (SMR) and test of the null hypothesis: SMR = 1. It is shown how one can compute the power of the test. A numerical example is given.
