similarity matching
a data approach that attempts to identify similar individuals based on data known about them
Link Prediction
a data approach that attempts to predict a relationship between two data items
Data reduction
a data approach that attempts to reduce the amount of information that needs to be considered to focus on the most critical items (highest cost, highest impact)
predictor (independent/explanatory) variable
a variable that predicts or explains another variable
response (dependent) variable
a variable that responds to or is dependent of another
