Predictors
Predictor
variables are characteristics associated with the patient. For
example, common predictor variables might include:
-
Demographics
(age, sex)
-
Symptoms
(e.g. pain, dyspnea)
-
Risk
factors at presentation (e.g. related to the severity of disease)
-
History
characteristics (e.g. related to previous disease course),
and
-
Comorbidity
(presence of other disease or diseases).
Statistically
speaking, predictors are the independent variables X in a prediction
problem. We also refer to predictors as "covariables."
