In particular, a long-term (one-year) measurement result of the spatial indoor carbon dioxide (CO2) concentrations in this office was used as a basis to investigate the probable errors due to the choices of sampling locations.
We propose that environmental heterogeneity can either mask or emphasize differences between neutral and non-neutral dynamics, depending on choices of sampling design and analytical approaches.
This procedure (both steps 1 and 2) is repeated 1000 times for each of 18 choices of sampling fraction, α, with values 0.01, 0.02, … 0.1, 0.2, … 0.9.
First, is this just some data anomaly resulting from selective choice of sample or quirks of the analysis?
It was later shown that the choice of sample locations could significantly impact the accuracy of resulting surrogates.
The choice of sample design, its rationale, and benefits and challenges of design decisions are described in this study.
Such a choice of sample number is based on the fact that the MC sample number should be chosen by the formula (M=(Delta x)^{-2s}) in (20).
Although the effects of gravity were minimised by choice of sample orientation, we show that such effects can only be eliminated in a microgravity environment.
The first choice of sample years drops only the 1997 cohort, which took the SAT during the election cycle in which Prop 209 was on the ballot.
