These seem to me powerful and valid.
Meta-analysis is a powerful and valid tool for combining rare outcomes, provided that appropriate methods are used which avoid large sample approximations [ 14].
Here we report the combination of BSA and RNA-seq as a powerful and valid approach for quantifying differential transcript expression and for cost-efficient identification of genes underlying γ-decalactone variation in cultivated strawberry.
The IV approach requires the use of at least 1 'instrument' which is a variable that is powerful and valid and correlates with treatment but is uncorrelated with unobserved determinants of the dimension of health or clinical endpoint under study [ 35].
This approach is designed to be both statistically powerful and biologically valid.
The relatively small variation observed within these prevalence rates across the different treatment stages, along with the large collective sample size of the meta-analysis (4494), suggests that these conclusions are valid, powerful and robust summaries of the data available.
The above method is a powerful means of implementing an authoritative and valid national QI system, in both developed and developing countries, before EMRs become the norm.
By a change of variable and the definition of c δ, we have again: Remark 2. Observe that: As an application of the operator fractional derivative D δ, we will give a characterization of the potential spaces, which is simpler and more powerful, valid for any 1
Rasch analysis is a powerful statistical technique for developing high-quality and valid questionnaires.
Text conferencing is a long-distance communication tool that is simple, powerful and cheap [ 10], all reasons why it is a useful and valid tool for the objectives.
For passerine birds, a powerful, ecologically valid method for inducing early-life food competition, and hence lowering early-life food availability, is manipulation of brood size within the species' natural range of variation (Gil, Bulmer, Celis, & López-Rull, 2008; Naguib, Riebel, Marzal, & Gil, 2004; Verhulst, Holveck, & Riebel, 2006).
