For this specific problem, the fitness function, the algorithm of genetic selection, crossover and mutation are designed to ensure the diversity of kernel function and more selected chances of optimal individual in evolution process.
If one takes the set of regions for calling a combination positive that gives a good ROC curve in a random sample of data, it may give a poor ROC curve in another random sample of the data, simply due to selecting chance patterns in the first sample.
In adult patients VRE account only for a certain percentage of all intestinal enterococci and non-selective screening would most likely be unable to select (by chance) for resistant variants [ 21].
Partly owing to how amendments have been selected, the chances of an assault on the economic policies embraced by Osborne succeeding seem limited.
The statistical significance reported above was calculated considering the probability of selecting by chance in the list of differentially expressed genes exactly 52 and 73 genes in common with the 153 previously identified (hypergeometric distribution).
Given the non-optimal filter, sizes were used each 2 SDs closer together than the optimal filter sizes, the chance of such suboptimal filters being selected by chance is very small, particularly if multiple phantom acquisitions are performed for filter selection (for instance, three repeats are recommended in the NEMA Standard [6]).
Nine networks were found significantly enriched with scores ranging from 9 to 19 (data not shown), the probability for a network to be selected by chance (score<3) decreasing when its corresponding score value increases.
Brown archaeoastronomers may justify this assumption through reading historical or ethnographic sources, while Green archaeoastronomers tend to prove that alignments are unlikely to be selected by chance, usually by demonstrating common patterns of alignment at multiple sites.
Only ∼30 genes were expected to be selected by chance using this statistical technique (see Materials and Methods for details).
The accuracy obtained with the worst-wKIERA-ranked variables is close to random classification as expected and shows that the best-ranked variables were not selected by chance.
