WebThe so-called permutation test, introduced by R. A. Fisher in the 1930s, is sometimes recommended for comparing means. The method is somewhat similar in spirit to the bootstrap, but a fundamental difference between it and the bootstrap is that the bootstrap resamples with replacement and the permutation test does not. http://wise.cgu.edu/wp-content/uploads/2015/04/Introduction-to-Resampling-Techniques-110901.pdf

WebPermutation tests rely on resampling the original data assuming the null hypothesis. Based on the resampled data it can be concluded how likely the original data is to occur under the null hypothesis. Bootstrap The best example of the plug-in principle, the bootstrapping method. ... The two key differences to the bootstrap are: WebWe decide that we will use the difference between the sample means as a test statistic, and we will consider a p-value of 0.05 to be statistically significant. For efficiency, we write the function defining the test statistic in a vectorized fashion: the samples x and y can be ND arrays, and the statistic will be calculated for each axis-slice ...

WebPermutation and bootstrap test are two surrogate tests. Permutation performs drawing of data samples without replacement, and bootstrap performs drawing with replacement. In theory, bootstrap is more valid … WebI have also read that it is often useful to give a confidence interval along with a test, which is created using bootstrap resampling rather than permutation resampling. Could you explain (or just give the R code) how a confidence interval is constructed (i.e. for the difference between the means of the two samples in the above example) ?
