The standard approximate intervals based on maximum likelihood theory, , can be quite misleading. In practice, tricks based on transformations, bias corrections, and so forth, are often used to improve their accuracy. The bootstrap confidence intervals discussed in this article automatically incorporate...
Bootstrapping is a nonparametric, but computer intensive, estimation method. In this paper we present the results of a simulation study on the behavior of three 95% bootstrap confidence intervals (i.e., SB, PB and BCPB) for estimating the larger-the-better signal-to-noise ratio when the ...
To ensure the reproducibility of results, the bootstrapping SEED was set to 1000. As per the bootstrap method, an indirect effect is considered statistically significant if the value 0 falls outside the confidence interval (in this case, the CI is set at 95%). Conversely, when the value ...
We calculated the pairwise difference between methods (using subjects as cases) and computed confidence intervals and significance using 20,000 bootstraps (this is equivalent to using a paired t-test, although, unlike a t-test, it does not require the data to be normally distributed). When ...
A bootstrap resampling method was used to test the significance of the mediational paths, using 5000 bootstrap samples and 95% confidence intervals (Kline, 2023). The significance level defined was < 0.05 for all the analyses. Results A confirmatory factor analysis was conducted to test ...
At each dose level, we propose using a bootstrapping approach to determine the confidence intervals of the synergy scores. To determine a bootstrap dose–response matrix, we sample the responses for each dose combination from a normal distribution Nμ,σ, where μ and σ are the mean and ...
progressors compared to non-progressors (bootstrapping, two- sided p < 0.001) (Fig. 6H), but this was not seen in the GZMB+ com- partment. By comparing the frequency of the GZMB+ phenotype within clonally expanded T cells from progressors and non-pro- gressors, we observed a ...

Point estimates and 95% bias-corrected bootstrap confidence intervals (95% CIBC) with 5000 bootstrap samples were calculated and reported for each of the proposed direct and indirect pathways (Hayes & Scharkow, 2013). As in Study 1, the model fit was evaluated by means of CFI, TLI (>...
We report 95% bootstrap confidence intervals to test the interactions on statisti- cal significance and Cohen's f2 (Cohen, 1988) as an indicator of effect size for the interactions, where 0.02 is a small effect, 0.15 is a medium effect, and 0.35 is a large effect. A confidence interval ...
