Hi there,
as part of a 2 x 2 contingency table analysis I would like
conditional probabilities (success rates) in a Bernoulli
experiment. In particular I want to test a null hypothesis p <= p0
versus the alternative hypothesis p > p0.
As far as I understand the subject, there are UMPU tests for these
types of hypotheses.
Now I know about R's "binom.test" but the help text is telling me it
will test only simple null hypotheses of the form p = p0.
The help page says that the "alternative" argument can be used to
specify "greater" as the alternative hypothesis. Isn't this what you
want?
binom.test package:ctest R Documentation
Exact Binomial Test
Description:
Performs an exact test of a simple null hypothesis about the
probability of success in a Bernoulli experiment.
