Sentence examples for estimates of sampling from inspiring English sources

FORCARB relies on FIA inventory tree volumes, and Heath and Smith [20] used reported FIA estimates of sampling error to arrive at a +/-5% sampling uncertainty estimate for volume (their uncertainty is expressed as a percentage of the median and represents +/-2 standard errors).

Because the sample was based on those who self-selected for participation rather than a sample based on probabilities, estimates of sampling error cannot be calculated.

In general, there was good agreement between the observed and the approximate predicted estimates of sampling variance (Table  1), but this deteriorated as family size increased, with the approximation generally underestimating the sampling variance.

FORCARB relies on FIA inventory tree volumes, and Heath and Smith [ 20] used reported FIA estimates of sampling error to arrive at a +/-5+/-5%pling uncestimate estimate for volume (their uncertainty is expressed as a percentage of the median and represents +/-2 standard errors).

The problem related to the assessment of aspen at stand-level inventories is that the low density of the aspen trees results in high estimates of sampling errors.

Because the sample is not random but is based on those who agreed to participate, no statistical estimate of sampling error can be calculated.

The above recovery procedures are motivated by the need to supply inventory estimates of AGB with an estimate of sampling and model errors.

Duplicate samples were therefore taken from the larger iceberg samples (S1, S4, KG1 and KG2) to provide a rough estimate of sampling variations.

But there is in any case no measurement of representativeness, and indeed no estimate of sampling variation within times as a baseline against which to compare sampling variation between times.

To get a rough error estimate of sampling effects, we also analyze the human data both from BiGG and KEGG, and two independent datasets from Jupiter's atmosphere.

Damage caused by parasitic fungi were excluded from the calculation in order to obtain an estimate of sampling intensity independent from the data analysed in this study (i.e. tree/fungus interaction records).
