Given a vector \(\mathbf\) denotes almost sure convergence. The nonparametric bootstrap involves randomly sampling data with replacement to form a “new” sample of data, which is referred to as a bootstrap sample. This document focuses on the np.boot function in the nptest R package, which combines the strengths of the bootstrap functionalities in the boot and bootstrap packages. Both the boot and bootstrap packages have several good features as well as some undesirable characteristics. D i 1 Mean Difference, D Known Paired samples (continued) The test statistic for the mean difference is a Z value: D D Z D n Where D hypothesized mean difference D population standard dev. Paste the data to the Sample Editor by using Ctrl+v (Windows) or Command+v (macOS). standard deviation of the difference scores, D, is known n is the number of pairs in the paired sample. Statdisk is designed for users of the Triola Statistics Series textbooks, published by Pearson Education. The bootstrap package, which is written by the creator of the bootstrap (Brad Efron), is another popular package for nonparametric bootstrapping. Make judgments about the size of the standard error of the estimate from a scatterplot Compute the standard error of the estimate. Get started by choosing an analysis, exploring data, or opening a Triola Statistics data set from the menus above.

The default install of R comes with the boot package, which is a collection of bootstrap functions that were originally designed for S (the predecessor of R). Unlike classic statistical inference methods, which depend on parametric assumptions and/or large sample approximations for valid inference, the nonparametric bootstrap uses computationally intensive methods to provide valid inferential results under a wide collection of data generating conditions. Nonparametric bootstrap sampling offers a robust alternative to classic (parametric) methods for statistical inference.
