Predictors: A predictor is a factor that increases the likelihood of a particular outcome later on. For example, smoking is a predictor of lung cancer. Smoking does not guarantee lung cancer, but since it increases the probabilities of lung cancer it is a predictor of lung cancer. Poor school attendance combined with course failure is a predictor of high school dropout. They do not guarantee dropout, but since there is a causal relationship, they are predictors of dropout. Unlike simple correlates, predictors are causes of an outcome.
