test.add(participants_a, conversions_a);
test.add(participants_b, conversions_b);
auto probabilities = test.probabilities();

Supports up to 4 variants

Count Data

auto test = bayestest::CountTest();
test.add(events_a, exposure_a);
test.add(events_b, exposure_b);
auto probabilities = test.probabilities();
