Watterson's θ and π are coalescent-based estimators of the population mutation rate (θ = 2Neμ) assuming standard neutral conditions and infinite sites or infinite alleles, respectively, that are useful as a sample-size adjusted measurement of nucleotide diversity.
I sit at my keyboard, making mental calculations, adjusting measurements, checking lists of ingredients, translating words out of Catalan into a language more familiar.
All studies that provided adjusted measurements included age in the analysis.
We described spatial variability by computing the coefficient of variation (CV) of temporally adjusted measurements across all sessions.
Since there was a wide range of gestational age at each visit, these measurements are used in the analyses as gestational age adjusted measurements [ 110].
Total BTEX levels exhibited the most spatial variability, followed by benzene and formaldehyde (coefficient of variation of temporally adjusted measurements of 0.57, 0.35, 0.22, respectively).
Between-array normalization methods have been developed to reduce these array-to-array variations by adjusting measurements at a global level.
Spatial variability, estimated by the CV across all temporally adjusted measurements, was greatest for BTEX, followed by benzene, then formaldehyde (CV of 0.57, 0.35, 0.22, respectively).
