The percentile bootstrap CI are con- structed by taking the lower 2.5% and the upper 97.5% value of each parameter estimate from runs regardless of conver- gence status (with exceptions for abnormal terminations), as this interval should cover the true value of the parameter esti- mate ~ ...
Confidence intervals calculated using 1000 bootstrap replicates. 6.1. Method We collected 2036 responses via participants in a separate unpublished project in which we investigated the relationship between objectively-tracked Xbox playtime and well-being. In this study, participants completed the pruned ...
The percentile bootstrap performs the worst in all situations, and has coverage systematically below 95%, including for normal distributions. In addition to coverage, it is useful to consider the width of the CIs from the different techniques. Confidence interval median width, based on the same ...
In Chapter 10 on inference for regression, we’ll revisit our regression models and analyze the results using the tools for statistical inference you’ll develop in Chapters 7, 8, and 9 on sampling, bootstrapping and confidence intervals, and hypothesis testing and pp-values, respectively....
the higher the replacement probability. The ratio between the coefficients of the two variables is roughly 4.5, indicating the productivity differential necessary to compensate a unit tax for the use of a robot. The 95% confidence interval of the ratio of coefficients (found via bootstrapping) is...

Concerning general model fit, Pearson’s χ2-goodness-of-fit (bootstrap) test suggested conformity of the data to the Rasch model (p= .19). Andersen’s conditional likelihood ratio tests and all of the nonparametric T10-statistics (including the examination of the effects of re-testing) indi...
