Estimation is a common goal in such applications and typically involves modeling the probability of disease as a function of available covariates. In recent years, several authors have developed regression methods to accommodate the complex structure of group testing data but often under the assumption that covariate effects are linear. Although linearity is a reasonable assumption in some applications, it can lead to model misspecification and biased inference in others. To offer a more flexible framework, we propose a Bayesian generalized additive regression approach to model the individual-level probability of disease with potentially misclassified group testing data. Our approach can be used to analyze data arising from any group testing protocol with the goal of estimating multiple unknown smooth functions of covariates, standard linear effects for other covariates, and assay classification accuracy probabilities. We illustrate the methods in this article using group testing data on chlamydia infection in Iowa.<\/jats:p>","DOI":"10.1093\/biostatistics\/kxaa003","type":"journal-article","created":{"date-parts":[[2020,1,13]],"date-time":"2020-01-13T20:11:24Z","timestamp":1578946284000},"page":"873-889","source":"Crossref","is-referenced-by-count":13,"title":["Generalized additive regression for group testing data"],"prefix":"10.1093","volume":"22","author":[{"given":"Yan","family":"Liu","sequence":"first","affiliation":[{"name":"School of Community Health Sciences, University of Nevada, Reno, 1664 N.
