Bayesian estimation of variance partition coefficients adjusted for imperfect test sensitivity and specificity
Kostoulas, P.; Leontides, L.; Browne, W. J.; Gardner, I. A. (2009)The variance partition coefficient (VPC) measures the clustering of infection/disease among individuals with a specific covariate pattern. Covariate-pattern-specific VPCs provide insight to the groups of individuals that ... -
Bayesian mixture models for partially verified data: Age- and stage-specific discriminatory power of an antibody ELISA for paratuberculosis
Kostoulas, P.; Browne, W. J.; Nielsen, S. S.; Leontides, L. (2013)Bayesian mixture models can be used to discriminate between the distributions of continuous test responses for different infection stages. These models are particularly useful in case of chronic infections with a long ... -
A Bayesian Weibull survival model for time to infection data measured with delay
Kostoulas, P.; Nielsen, S. S.; Browne, W. J.; Leontides, L. (2010)Survival analysis methods can be used to identify factors associated with the time to induction of infection In the absence of a perfect test, detection of infection is generally delayed and depends on the duration of the ... -
Sample size estimation to substantiate freedom from disease for clustered binary data with a specific risk profile
Kostoulas, P.; Nielsen, S. S.; Browne, W. J.; Leontides, L. (2013)Disease cases are often clustered within herds or generally groups that share common characteristics. Sample size formulae must adjust for the within-cluster correlation of the primary sampling units. Traditionally, the ...
