WebJun 17, 2015 · The binomial test is an exact test that uses the binomial distribution to get an exact count of how often p ^ would happen under the null hypothesis. You can run it in R using binom.test. It makes no assumptions about n p or n ( 1 − p). However, since it is an exact test, not every p-value is possible. Share. WebRun an unpaired hypothesis test for samples from two conditions using nbintest. The assumption is that the data came from a negative binomial distribution, where the variance is linked to the mean via a locally-regressed smooth function of the mean as described in [1] by setting 'VarianceLink' to 'LocalRegression'.
