Volcano monitoring networks have been installed and maintained to detect precursory unrest as early as possible for timely hazard warnings (Guffanti et al. 2010; Ewert et al. 2005).
If the data are substantially skewed, 80% power would be maintained to detect a minimum effect size of 0.525 [ 63, 64].
The statistician takes comfort in the fact that by attaining the original number of target events specified in the design, power is maintained to detect the relative difference between the treatment arms whatever the underlying median time to outcome.
It is interesting to note that starting with a study design with a higher power (90% rather than 80%) means that even at the higher level of underestimation given in Table 1 (a 25% difference), reasonable power is maintained to detect the original absolute target (75%).
However, surveillance must be maintained to, eventually, detect emerging types or variants selected by the new pressure imposed by vaccination.
HFW maintained power to detect microsatellite selection after mutation selection equilibrium, although power was low to moderate (fig. 2 D).
As part of the International Health Regulations 2005 core surveillance and response capacity requirements, each Member State must develop and maintain capabilities to detect, assess, and report disease events nationally and internationally to WHO within 48 hours of confirmation.
As part of IHR 2005's core surveillance and response capacity requirements, each state party has to develop and maintain capabilities to detect, assess, and report disease events at the local, intermediate, and national levels (article 5.1, annex 1).
Using the r avg statistic, one would need to study 1.37 (= 1/0.73), 1.37 (= 1/0.73), 1.54 (= 1/0.65), and 7.69 (= 1/0.13) times as many samples to maintain power to detect disease genes as would be necessary if one had full ancestry information, using the panels based on δ, F ST, 21 k random markers, and 2 k random markers, respectively.
Therefore, to have a single LOD score threshold regardless of sample size, the IBD scale factor must increase as the sample size increases and the size (complexity) of the fitted Beagle model must stay approximately constant, to maintain power to detect IBD as sample size increases.
Analyses on different levels of taxonomic resolution showed that the level of family maintained sufficient information to detect the impacts of coastal defence structures on benthic assemblages.
