Abstract:

Calculation of sensitivity and specificity of diagnostic indicators in medicine depends on knowledge of a "gold standard"; that is, knowing for certain whether each patient has or doesn't have a disease. But this is not always true; there is error in many areas of diagnosis, and this biases the estimates of sensitivity and specificity. Rindskopf and Rindskopf (1986) discussed some of the benefits of latent class diagnosis in this case. Additional insights have been made since then, and these will be discussed in this talk.
