Furthermore, this association was statistically nonsignificant in the age-matched study with more statistical power.
Bigger GWAS, with more statistical power, may help a bit, but clearly new methods are needed.
Larger studies generally have more statistical power, but smaller, in-depth studies can be equally valuable.
Aligning the data before applying Friedman ranks was shown to produce more statistical power than simply analyzing Friedman ranks.
In doing so, it tests the random walk hypothesis by employing unit root tests that are designed to have more statistical power against non-linear alternatives.
The first three make the responses of the two models more different, and the last provides more statistical power.
Some of the analyses focused on the five most prevalent diagnostic groups, to gain more statistical power.
Such a strategy strengthens evidence, giving the results more statistical power and, therefore, more credibility than the individual studies [18].
Another shortcoming of this study was the relatively small sample size, so it is important to move forward with a larger study to gain more statistical power.
More specifically, despite a larger sample size, the case-noncase design does not necessarily provide more statistical power.
Using a continuous exposure will give more statistical power if a log-linear association exists between exposure and risk of a defect.
