Print on Demand. This book explores a parametric estimation procedure that estimates the prevalence of HIV from pooled samples. It combines various samples into a pool and tests the pool, rather than testing each individually. Existing pooled testing procedures estimate the prevalence using dichotomous test outcomes, which can eliminate useful information. To overcome this, the author develops a parametric procedure that utilizes continuous outcomes. This procedure employs a hierarchical pooling model and calculates prevalence using the likelihood equation. The likelihood equation is solved using an iterative algorithm, which yields accurate estimates for a fraction of the cost of existing procedures. The book is useful for statisticians, public health researchers, and policymakers interested in accurate and cost-effective HIV prevalence estimation methods and provides valuable insights into improving the methodology of pooled testing for disease prevalence estimation. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

- Statistics
Estimation of the prevalence of hiv is important for evaluating the current status of the aids epidemic and planning effective intervention programs. However, precise estimates are very difficult to obtain because hiv infection is not associated with any clinical symptoms. Because the interval between the infection time and the onset of the clinical symptoms of aids is very long, the total number of aids cases does not provide information on the recent incidence of hiv. Consequently, population surveys are the primary mode of hiv prevalence estimation.
This method screens an unbiased population sample using an antibody test, such as elisa, and estimates the prevalence from the number of positive tests. However, even this method has its limitations. Because participants in a survey must give their prior consent, self-selection bias can occur that results in an underestimation of the prevalence (gill, Adler and Day Also, the number of-tests is frequently limited by financial constraints that adversely affect the accuracy of the estimates.
