Compared to the fully deployed system, the bootstrap system will only cover a subset of the real call routing destinations.
The bootstrap sampling was based on stories rather than individual questions, to take into account the interdependence among questions of the same story.
We use these bootstrap methods to assess measurements of local mean reversion or "pull" to the center of the distribution for short-term interest rates.
They also include geometrical effect, bootstrap current effect and separatrix effect, leading to complicated nonlinear behavior.

We call attention to the fact that the bootstrap of regularity can be done independently for stable derivatives and unstable derivatives.
As is usual in bootstrap arguments, the more complicated parts happen at the beginning, when we are allowed to assume fewer properties of the function.
We calculated confidence intervals by bootstrap resampling of genotypes (for model 1) or alleles (for model 2).
The bootstrap gives accurate power estimates only if the data closely reflect the underlying true parameters.
Initially we noticed that the bootstrap power estimates did not agree well with the power figures determined by simulation or analytically.
To understand the properties of the bootstrap, we first considered a much simpler data structure.
Values in parentheses are 95 % bootstrap confidence intervals ; values that are significantly different from 0 are in bold type.
The work goes further to show the parametric bootstrap has significant failings and no appreciable advantages over the non-parametric bootstrap.
The results of the selective bootstrap showed only a small difference from the non-selected method (results not presented).
The non-parametric bootstrap does seem suitable although slightly conservative.

In both analyses, bootstrap tests with 1000 replications were performed to assess the support value for each internal branch of the trees.
What sort of innate structure is needed to ' bootstrap ' into syntax ?
However, we want to emphasize that both approaches, standard asymptotics and the bootstrap, are based on asymptotic arguments.
Our results suggest that the use of bootstrap critical values is essential in reducing spurious rejections of the unitroot hypothesis.
In this procedure the cointegration matrix is reestimated for each bootstrap sample.

Figure 3 presents the incremental cost-effectiveness plane using the incremental cost and effectiveness estimates from the 200 bootstrap samples.
The bootstrap procedure generates a large number of independent samples by sampling with replacement from the source data.
The size of each bootstrap sample taken is the same size as the original sample.
However, the double bootstrap did not exhibit this pattern.

Quantifying precision of mark-recapture estimates using the bootstrap and related methods.
Estimating uncertainty ranges for costs by the bootstrap procedure combined with probabilistic uncertainty analysis.
Confidence probabilities from bootstrap tests of interior branch lengths are shown.
The bootstrap allows inferences to be made directly from the actual data, while loosening the parametric assumptions that may not hold in a particular case.
The numbers at the branch nodes indicate the results of the bootstrap analysis.
The above property of the bootstrap was also investigated for contrast mapping.
Estimates were deemed significant if 95 % of the bootstrap values were found to be greater than zero.
The tree from neighbourhood-joining analysis with the percentage of replications (bootstrap; 1000 replications) is shown.
Thus, although this is not always clear in the literature, conditional and unconditional bootstrap strong laws are one and the same.
Secondly, run-down of social provision justified by the argument that the less well provided must" pull themselves up by their own bootstraps".
Nevertheless, the actual bootstraps will require different arguments since the non-commutativity will prevent some of the rearrangements that we did in the commutative case.
We call attention to the fact that formula will be the basis for subsequent bootstraps.
The bootstrap's distinctive advantage over parametric inference is clearest when there is no parametric inference alternative.
The bootstrap's main advantages are in dealing with skewed data and its ability to take correlations between costs and effects into account.

However, the relative performances of the two methods was much more dependent upon factors such as the bootstrap's bias in the second moments and the correlation combinations.
Despite low bootstrap values at many individual internal nodes, the clusters formed and arrangement of taxa within them were largely identical.
Clearly, for this test bootstrap support values are more conservative measures of support than either of the posterior probabilities calculated above.
