BIFROST—block recursive models induced from relevant knowledge, observations, and statistical techniques

TL;DR: In this paper, the copy number of a chromosome in a fetus in the context of non-invasive prenatal diagnosis is determined using the measured genetic data from a sample of genetic material that contains both fetal DNA and maternal DNA.

TL;DR: In this article, the authors identify characteristics of sow behaviour and parturition related to early piglet mortality in loose-housed farrowing sows, and use a Graphical Chain Model (GCM) to model the relationships between perinatal behaviour, periparturient individual conditions (time of day of parture, rectal temperature 1-3 days postpartum) and causes of early Piglet mortality.

TL;DR: Variables related to the birth process had no direct connection to thermoregulatory success, but were additive in the explanation of piglet behavior, and birth weight is the most important single factor in successful recovery from postnatal hypothermia.

TL;DR: Danish organic dairy production is characterized by a low input of antibiotics for udder treatment and a high input of other mastitis control procedures, and characteristic patterns in these results are identified.

TL;DR: In this paper, the problem of selecting one of a number of models of different dimensions is treated by finding its Bayes solution, and evaluating the leading terms of its asymptotic expansion.

TL;DR: In this article, the authors consider the problem of model selection and accounting for model uncertainty in high-dimensional contingency tables, motivated by expert system applications, and propose a panacea by the standard Bayesian formalism that averages the posterior distributions of the quantity of interest under each of the models, weighted by their posterior model probabilities.
