Sentence examples for statistic such as from inspiring English sources

In traditional statistical methods, a test statistic such as Student's t or Fisher's F is compared to a mathematically derived continuous probability distribution of that statistic under the null hypothesis.

It would be unfair to claim that any one statistic, such as newly developed "value-added data," should stand alone as definitive evidence of a teacher's effectiveness.

Finally, we show that the system design based on the channel distribution outperforms a design that is based on a specific channel statistic such as the mean value.

Hearing another umbrella statistic such as "heart disease is the leading killer in our country" has little impact, if any.

Having obtained point estimates for all the genes, studies of differential expression between pairs of phenotypes are carried out by comparing the collections of point estimates under the phenotypes, using a t-type statistic such as in SAM [73], Cyber-T [74] or Limma [75], all of which rely on the availability of replicate subjects in each phenotypic condition, for estimation of variances.

Alternatively, the user can simply rank called peaks according to some peak statistic (such as number or tags, fold enrichment over background, or p-value) and analyze only the top n-peaks where n is adjusted according to the researchers' desired stringency.

The utility of a modified t-statistic such as the SAM-statistic or the t-type score has been demonstrated by some researchers (Baldi and Long, 2001; Broberg, 2003), and we evaluated the utility of the t-type score in small microarray experiments.

The median was chosen as the summary measure of expression across the eight arrays (for each oligonucleotide) because the median has been shown to have better performance than mean-based statistics, such as the t-statistic or the SAM statistic, in identifying spiked-in RNAs using small sample sizes [ 22].

Traditional statistics, such as t-statistic and SAM [ 16, 17], will not work for detecting multiple coexisting genes caused by the heterogeneity of cancer.

The optimal p-value threshold algorithm can also be applied to other association test statistics, such as the FBAT statistic, test statistics based on linear and logistic regressions from unrelated subjects, or test statistic based on mixed-model from related subjects, as long as an appropriate permutation strategy is used.

In microarray experiments, the end-stage analysis usually consists of simple two-sample test statistics such as the t-statistic or the Wilcoxon Rank Sum test statistic to test for differential expression.
