npExact - Exact Nonparametric Hypothesis Tests for the Mean, Variance and
Stochastic Inequality
Provides several novel exact hypothesis tests with minimal
assumptions on the errors. The tests are exact, meaning that
their p-values are correct for the given sample sizes (the
p-values are not derived from asymptotic analysis). The test
for stochastic inequality is for ordinal comparisons based on
two independent samples and requires no assumptions on the
errors. The other tests include tests for the mean and variance
of a single sample and comparing means in independent samples.
All these tests only require that the data has known bounds
(such as percentages that lie in [0,100]. These bounds are part
of the input.
