While it is unlikely that this model accurately reflects the true association between Y T and Y E, this model may still be useful because the sample size in phase I-II oncology trials is limited and we may lack the sample size to precisely estimate ψ1 and ψ2.
However, a large SAR scene sample is required to precisely calculate wind statistics.
A bias of −9.0 V was applied to the sample in order to precisely determine the low kinetic energy cutoff, as discussed in ref. 50.
This study was undertaken to establish one of the most reliable sampling methods and to precisely evaluate the bias involved in the collection of airborne pollutant samples.
The sets of samples are formed to precisely answer the biological questions of interest.
14 26 27 Most existing studies of the accuracy of depression screening tools, including the EPDS, 30 however, have been conducted in samples too small to precisely estimate accuracy.
For the Mehta score [ 8] we were unable to match ethnicity in the development sample, and were unable to precisely match the field MI within 3 weeks, or the type of valve procedure (mitral versus aortic).
The small number of actively smoking women in our sample limited our ability to precisely estimate relationships between prenatal tobacco smoke exposure and meconium tobacco smoke metabolites among active smokers.
Further genetic analyses coupled with a fine grained sampling design are needed to precisely identify the borders of genetic stocks.
These findings suggest that small additive effects on protein levels are common and that much larger numbers of CSF samples will be required to precisely determine associations between Alzheimer's disease risk variants and biomarker levels.
