The DNA database search controversy revisited: Bridging the Bayesian - Frequentistic gap

چکیده

Two different quantities have been suggested for quantification of evidence in cases where a suspect is found by a search through a database of DNA profiles. The likelihood ratio, typically motivated from a Bayesian setting, is preferred by most experts in the field. The so-called np rule has been suggested through more frequentistic arguments and has been suggested by the American National Research Council (NRC) and Stockmarr (1999). The two quantities differ substantially and have given rise to the DNA database search controversy. Although several authors have criticized the different approaches, a full explanation of why these differences appear is still lacking. email: [email protected]

Genetic Analysis of Rare Disorders: Bayesian Estimation of Twin Concordance Rates

Twin concordance rates provide insight into the possibility of a genetic background for a disease. These concordance rates are usually estimated within a frequentistic framework. Here we take a Bayesian approach. For rare diseases, estimation methods based on asymptotic theory cannot be applied due to very low cell probabilities. Moreover, a Bayesian approach allows a straightforward incorporat...

Subgeneric classification of Linaria (Plantaginaceae; Antirrhineae): molecular phylogeny and morphology revisited

Linaria Mill. (Plantaginaceae) with about 160 spp. is the largest genus of the tribe Antirrhineae. We conducted phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer region (ITS) and chloroplast DNA (rpl32-trnL) sequence data to test the monophyly of currently recognized sections in Linaria. For this purpose 86 species representing seven sections of Linaria and one species ...

Bridging the Gap Between Research and Policy and Practice; Comment on “CIHR Health System Impact Fellows: Reflections on ‘Driving Change’ Within the Health System”

Far too often, there is a gap between research and policy and practice. Too much research is undertaken with little relevance to real life problems or its reported in ways that are obscure and impenetrable. At the same time, many policies are developed and implemented but are untouched by, or even contrary to evidence. An accompanying paper describes an innovative progr...
