Use of latent class models to accommodate inter-laboratory variation in assessing genetic polymorphisms associated with disease risk.

Abstract excerpt

BACKGROUND: Researchers wanting to study the association of genetic factors with disease may encounter variability in the laboratory methods used to establish genotypes or other traits. Such variability leads to uncertainty in determining the strength of a genotype as a risk factor. This problem is illustrated using data from a case-control study of cervical cancer in which some subjects were independently...
