Test of Significance about Two Population Proportions
… for testing if there is a difference between two population proportions. The size of the test is exact in the sense that it is the maximum probability of rejecting a true null hypothesis. A method is given for determining a greatest lower bound on the power of the test over a region in which the …

Diagnosis, epidemiology and immunologic consequences of copper deficiency in calves
… test results than the z-distribution for population proportions. In relation to copper supplementation there were no statistically significant differences in the immunologic parameters studied. This however, may not represent the true benefit copper supplementation may have on copper …

Insights from serological surveillance in infectious disease epidemiology
… indicators of the true burden of infection in a population due to varying rates of subclinical infections, non-specific symptoms, and heterogeneity in health seeking behaviour. Serological surveillance, which tests for immune markers such as antibodies generated in response to an infection, …
