Excerpt
Excerpt: The characteristics of a screening test are usually expressed by sensitivity and specificity. The sensitivity (specificity) of a test is the probability that a person having (not having) the disease is correctly classified. The prevalence rate of cancer is frequently estimated through the use of a screening test. The effects of the characteristics of the test in estimating disease rates have been investigated and methods are proposed for adjusting the disease rates (I$) with the characteristics of the test assumed to be known. Methods of estimating the characteristics of the test have also been developed by several authors. Tanenbein (8) considered the use of a double sampling scheme. Hochberg (4) extended this to provide a basis for inference from general multidimensional contingency tables. Goldberg and Wittes (5) applied the capture-recapture model. Hui and Walter (6) suggested that data are available from any two populations with different prevalences and applied the method of maximum likelihood in estimating simultaneously the characteristics of the test and the prevalence rates in both populations. Yanagawa et al. (7) and Yanagawa and Kasagi (8) introduced a study design in which a person is tested repeatedly at least three different times, and they developed amethod of estimating prevalence and incidence rates of disease together with Deoartment of Mathematics..
