Sentence examples for by random chance using from inspiring English sources

We then tested whether a cluster contained more of a particular biological relationship than would be expected by random chance using the hypergeometric distribution with a modified Bonferroni correction as implemented in GeneMerge [25].

The MVH system segregates experimental peaks into three intensity classes and measures the point probability of matching a given combination of peaks by random chance using a multivariate hypergeometric distribution [17].

Next, the overlap between genes with high confidence hits of the site in their upstream regions and the set of genes expected to be regulated by the site was assessed by estimating the probability of obtaining the observed amount of overlap (enrichment) by random chance using the hypergeometric distribution.

Therefore, to ensure that the pairs of homologous genes implied by these BLAST alignments were indicative of true pairs (as opposed to alignments that could occur simply by random chance), we used three filters: an E-value threshold of 10-6, alignmentent coverage requirement, and the requirement that the alignment was to a gene with assigned function.

The probability of each term being identified by random chance was calculated using Fisher's exact test.

Novel sequence motifs that were present in PR binding regions statistically significantly more frequently than expected by random chance were identified using Gibbs Motif Sampling [ 45] or MEME [ 46].

The significance of these results was evaluated using the binomial cumulative distribution function where the probability (pk) of observing at least 226 (or 271) significant chemical-disease (or chemical-disease category) relationships by random chance was determined using the data for 4559 chemicals from CTD and for 204 diseases in GAD.

The significance value of a given canonical pathway, a measurement of the likelihood that the pathway is associated with the data set by random chance, was calculated using a right-tailed Fisher's Exact Test, and values of p < 0.05 were assumed to be statistically significant.

Therefore, our age predictor performed significantly better than would be expected by random chance, and can be used to study the population accurately.

A score of 3 or higher has a 99.9% confidence level of not being generated by random chance alone and was used as the cutoff for identifying protein networks.

The probability that all of these show the same deviation by random chance is negligible (i.e. if p-values for each exon within the segments are combined using Fisher's Method, the resulting p-value approaches zero).
