A gene list can be identified on a basis of a certain statistic threshold such as p < 0.005.
Consequently, quantitative comparisons of journals on the basis of a single impact statistic are fraught with problems for a field like evolutionary biology.
The Kaplan Meier survival estimates of time to IBTR suggested differences between the older (age ≥ 40 years) and younger (age < 40 years) women after 5 years of follow-up but the difference was not significant on the basis of a log-rank test statistic (p = 0.47).
It evaluates the significance of a certain match on the basis of the statistic background of all candidate matches.
Brem et al. (2002)—whose data included hybridizations from numerous segregants of unknown genotype, as well from parental samples of known genotype further augmented this approach: using parental data, candidate SFPs were identified on the basis of a high moderated t-statistic.
Finding the winner of the National is not supposed to be easy, after all, yet trends devotees will cheerfully ignore as much as a third of the field on Saturday with barely a second thought, on the basis of this statistic alone.
On the basis of this statistic, at least, Sa'adiah is, as noted above, the most important "influence" upon Ibn Ezra.
In this sense our results support the validity of the idea of discriminating between ancient and contaminant DNA on the basis of the statistic of cytosine deaminations as proposed by Helgason and colleagues [42].
A p-value determined on the basis of the test statistic is compared with a significance level α: {text{if}},p le alpha text to {mathcal{H}}_{0}, {text{is rejected in favour of}}, {mathcal{H}}_{1} {text{if}},p > alpha to {text{there is no basis to reject}},{ mathcal{H}}_{0}.
An optimal cutoff value was identified on the basis of a measure of heterogeneity with the log-rank test statistic with respect to overall survival.
