regression
Significado: A return to a former or less developed state; in psychology, reverting to earlier behaviour patterns under stress; in statistics, a method for modelling the relationship between variables.
Regression has distinct meanings across disciplines. In psychology, it is a defence mechanism where an adult reverts to childlike behaviour when overwhelmed. In statistics, regression analysis is one of the most widely used tools for predicting outcomes based on data. The phrase 'regression to the mean' describes the tendency for extreme values to move closer to the average over time.
