摘要： Multiple comparisons In statistics, the multiple comparisons or multiple testing problem occurs when one considers a set of statistical inferences simultaneously. Errors in inference, including confid... 阅读全文

摘要： For most hypothesis tests, we start with the assumptions and work forward to derive the sampling distribution of the test statistic under the null hypothesis. For permutation tests we will reverse the procedure, since the sampling distribution involves the permutations which give the procedure its n 阅读全文

摘要： Randomization Tests Constrained ordination methods such as CCA and RDA find the ' best possible' relationship (defined in a mathematical sense) between species composition and the environment. Therefo... 阅读全文

摘要： Randomization Tests We will begin with randomization tests, because they are closer in intent to more traditional parametric tests than are bootstrapping procedures. Their primary goal is to test some... 阅读全文

摘要： Randomization Tests (1 of 6) Most distribution-free tests are based on the principle of randomization. The best way to understand the principle of randomization is in terms of a specific example of a ... 阅读全文

摘要： The Cauchy–Lorentz distribution, named after Augustin Cauchy and Hendrik Lorentz, is a continuous probability distribution. As a probability distribution, it is known as the Cauchy distribution, while... 阅读全文

摘要： In probability theory, a log-normal distribution is a probability distribution of a random variable whose logarithm is normally distributed. If X is a 阅读全文
