netCAR takes into account the phylogenetic co-occurrence graph between COGs to restrict hypothesis space, and uses mutual information to evaluate the biconditional relation.
For example, one may restrict hypotheses to have no more than one reference to each ontology from GO.
Still, the challenge of testing evolutionary hypotheses is not restricted to hypotheses of human health and disease (Gluckman et al. 2011), and the AR and CAGn provide a excellent system in which to explore these complex and elusive forms of selection in the human genome.
In particular, we restrict the hypothesis space of possible recognition models by applying some advanced concepts from Statistical Learning Theory, so as to force the selection of models with good generalization ability but low computational complexity.
Each new piece of information whether the crystal structure of a drug bound to a protein or the identification of a labile site of reactive metabolite, or the general physicochemical properties of drug-space further restricts our hypothesis space in drug-space further
We believe that given a large number of genes and a small number of experimental conditions, it is more important to restrict the hypothesis space for data fitting.
However because the Bootstrap introduces a bias in the error estimates that is difficult to correct, the above procedure samples without replacement and tests only for a restricted null hypothesis (i.e., "bad" data split).
Until recently, association approaches were restricted to hypothesis-driven studies on candidate genes, as described in the following paragraphs.
The solutions offered by statistical rules – corrections for multiple hypothesis testing or restricting analysis to ex ante hypotheses – is inadequate.
Based on this classification and hierarchy which implies a main direction of information flow among periodic genes, we refine our hypothesis by restricting the set of genes from which we are searching the shortest paths to the SCC.
