FcnsByCatHypothTests: EnvStats Functions for Hypothesis Tests

Description

The EnvStats functions listed below are useful for performing hypothesis tests not already built into R. See Power and Sample Size Calculations for a list of functions you can use to perform power and sample size calculations based on various hypothesis tests.

Arguments

Details

For goodness-of-fit tests, see Goodness-of-Fit Tests. ll{ Function Name Description chenTTest Chen's modified one-sided t-test for skewed distributions. kendallTrendTest Nonparametric test for monotonic trend based on Kendall's tau statistic (and optional confidence interval for slope). kendallSeasonalTrendTest Nonparametric test for monotonic trend within each season based on Kendall's tau statistic (and optional confidence interval for slope). oneSamplePermutationTest Fisher's one-sample randomization (permutation) test for location. quantileTest Two-sample rank test to detect a shift in a proportion of the treated population. quantileTestPValue Compute p-value associated with a specified combination of $m$, $n$, $r$ and $k$ for the quantile test. Useful for determining $r$ and $k$ for a given significance level $\alpha$. serialCorrelationTest Test for the presence of serial correlation. signTest One- or paired-sample sign test on the median. twoSampleLinearRankTest Two-sample linear rank test to detect a shift in the treated population. twoSamplePermutationTestLocation Two-sample or paired-sample randomization (permutation) test for location. twoSamplePermutationTestProportion Randomization (permutation) test to compare two proportions (Fisher's exact test). varTest One-sample test on variance or two-sample test to compare variances. varGroupTest Test for homogeneity of variance among two or more groups. zTestGevdShape Estimate the shape parameter of a Generalized Extreme Value distribution and test the null hypothesis that the true value is equal to 0. }
