But the reality of the San Fernando Valley has long been more complex, and the 2000 census contained this striking nugget: Like the rest of Los Angeles, which stretches south below Mulholland Drive, the valley, north of Mulholland, is now nearly 50percentt Hispanic.
One important feature of the sampling plan was that either complex cluster samples or censuses of individuals, still belonging to clusters, were surveyed.
Here, we devise methods that preserve the in vivo assemblages of SCF complexes and apply quantitative mass spectrometry to perform a census of these complexes (the "SCFome") in various states.
PNAD and GATS Brazil used a four-stage complex probabilistic household sample (municipality, census tract, household and individual) and was representative of the national and regional levels.
By asking people to state their religion, or lack of it, the census was asking a complex question.
To measure and map this complex spatio-temporal relationship at the census block group level (n= 567), we examined a variety of models using integrated nested Laplace approximations and used the deviance information criterion to gauge model complexity and fit.
Across the 14 federal statistical agencies, complex surveys -- including the U.S. Census -- are designed and conducted by statisticians.
The principle behind these alternative applications, which have been termed 'sequence census' methods, is simple: complex DNA or RNA samples are directly sequenced to determine their content.
As noticed, forecasting census counts becomes increasingly more complex with increasing levels of uncertainty as one considers longer forecasts.
Such planning is further complicated by the difficulty of precisely capturing complex and varied migration patterns in the census.
