At present, the implementation of a registry-based sample design in Germany for such a representative sample of the migrant population is subject to potential restrictions (Salentin 2014): first, registry-based samples can be drawn only if the survey is of public interest; second, not all existing information can be used as a selection criterion.
With the advance of genotyping technology, large-scale genome-wide data has enabled estimation of the GRM from population-based samples, and now both family-based and population-based samples can be utilized to estimate heritability.
The multi-index model based on large samples can be used to predict risk of gastric cancer more accurately and effectively in clinical screening.
Misclassification rates calculated based on testing samples can be used to estimate the accuracy of the forests.
Although 'snapshots' of genetic patterns based on single samples can be extremely informative, the ability to divulge historical population processes that shaped current patterns of genetic variation is limited (Beaumont 2003; Miller and Waits 2003).
A typical 454 FLX run can net 1 000 000 sequences of 450 bases, and samples can be multiplexed using nucleotide barcodes.
Standard analysis methods based upon venous blood samples can be logistically challenging in resource-poor settings where much of the diabetes epidemic is occurring.
In addition to speed, the test has a second advantage over culture based methods in that samples can be treated to render them non- infectious.
As outlined above, the design of the exploratory phase based on representative pooled samples can be considered a limitation of our study.
If reasonably reliable prevalence estimates or data on new HIV diagnoses by age groups are available, a survey surveillance discrepancy factor for internet based or other convenience samples can be calculated for adjusting survey data for the total population, if necessary.
Based upon high electric fields, samples can be separated and detected quickly.
