N. Gay, ANALYSIS OF SEROLOGICAL SURVEYS USING MIXTURE-MODELS - APPLICATION TOA SURVEY OF PARVOVIRUS B19, Statistics in medicine, 15(14), 1996, pp. 1567-1573
A method for the analysis of age stratified antibody prevalence survey
s is developed. The age specific distribution of the quantitative resu
lts of serological antibody tests is modelled as a mixture of seroposi
tive and seronegative components. This yields maximum likelihood estim
ates of the prevalence at each age. The method is illustrated using da
ta from a previously reported survey of antibody to parvovirus B19.
