For binary data it is common to call the outcome ‘an event’ or ‘a non‐event’. For example, having your corn healed and resolved after three months of treatment may be an ‘event’. We often score an ‘event’ as 1 and a ‘non‐event’ as 0. These may also be referred to as a ‘positive’ or ‘negative’ outcome or ‘success’ and ‘failure’. It is important to realise that these terms are merely labels and the main outcome of interest might be a success in one context and a failure in another. Thus, in a study of a potentially lethal disease the outcome might be death, whereas in a disease that can be cured it might be being alive.
