Instance Method Details

#ab_add_conversion(experiment, alternative, identity, count = 1, implicit = false) ⇒ Object

Records a conversion in this experiment for the given alternative. Associates a value with the conversion (default to 1). If implicit is true, add particpant if not already recorded for this experiment. If implicit is false (default), only add conversion is participant previously recorded as participating in this experiment.
