The phrase "a more powerful test" is correct and usable in written English.
It can be used when comparing the strength or effectiveness of different tests or assessments.
Example: "In our study, we found that a more powerful test was necessary to detect the subtle differences between the two groups."
Alternatives: "a stronger test" or "a more effective test".
When bootstrap is utilized, however, a more powerful test than the bootstrapped D-W test can be designed.
A more powerful test for positive selection is provided by branch-site models, which test if certain codons are under selection in the foreground branch [19].
FDR is an alternative that controls the number of false positives that is equivalent to the Bonferroni method when there are no truly significant results; otherwise it is less conservative and therefore a more powerful test [46].
The identification of a subset of cases most likely to harbor disease-associated variants at a locus may permit the use of a more powerful test statistic that capitalizes on the hypothesized ordering of controls, cases, and select cases, with regard to the prevalence of rare variants.
A more powerful test for interaction between unlinked genes is a case-only test [ 16].
In the presence of heterogeneity in effect sizes, Stouffer's method can provide a more powerful test of association than the inverse variance method (47).
A statistically more powerful test of a shared adaptive response in gene expression is to compare all three polluted populations to all six reference populations.
This polymorphism set provides the opportunity for a far more powerful test of population structure than the aforementioned microsatellite approach.
The q-value measures the strength of the observed statistic, with respect to pFDR, and automatically corrects for multiple hypothesis testing, it is therefore a much more powerful test scheme.
We also find that using control groups, rather than a single control firm, yields more powerful test statistics.
However, we obtain more powerful test procedures in many situations, using nonuniform kernels.
