The method leads to an unbiased estimate of mean abundance via the Hansen-Hurwitz estimator (Thompson and Seber 1996).
* The latest year for which I could find an estimate of mean grade was 2005, where it was 3.45 (a B-plus).
Upon implementation of precipitation-decorrelation, a tightly bounded statistical estimate of mean annual Lake Tahoe evaporation is obtained, which closely matches independent measurement-based estimates.
Bias in the average sample estimate of mean stem volume, as a percentage of the average estimate, by stand and sampling method.
Using bootstrap resampling methods, we calculated 95%% confidence intervals for each model and compared results to a simple estimate of mean AGB from the NFI ground plot data.
Lice numbers varied significantly between cages on a single group, indicating that fish from several cages should be sampled to give a representative estimate of mean lice number on the farm.
As a widely accepted reduced-reference pixel-domain video quality measure, NTIA-VQM [28], used as an estimate of mean opinion score (MOS) here, shows a significant quality variation to account for the changes in content characteristics.
Nine sampling methods (random, stand-boundary, quasi-random, Zigzag transects, grid-based plots of four sizes and single-point) were simulated and applied repeatedly to each stand, and the bias and reliability of the estimate of mean stem volume calculated.
To compute the optimum log-likelihood value for each possible pair of leaf and question, the maximum likelihood estimate of mean parameters has to be first obtained by Equation 18.
An analysis based on the variability of our samples suggested that just 3 4 randomly positioned 1 ha plots would be sufficient to provide a reasonable estimate of mean TAGB in a landscape such as ours (with 95% confidence intervals being <10% of the mean).
Using the values in Table 5, the CI was calculated as follows: η eff = N / 1 + total DOF associated in the estimate of mean = 27 / 1 + 2 = 9, Open image in new window α = 1 − confidence limits 95%% = 0.05, Open image in new window F ratio = 1, 0.05, 18 = 4.41 tabulated, Open image in new window.
