regression

(rɪˈɡrɛʃən)
n
1. (Psychology) psychol the adoption by an adult or adolescent of behaviour more appropriate to a child, esp as a defence mechanism to avoid anxiety
2. (Statistics) statistics
a. the analysis or measure of the association between one variable (the dependent variable) and one or more other variables (the independent variables), usually formulated in an equation in which the independent variables have parametric coefficients, which may enable future values of the dependent variable to be predicted
b. (as modifier): regression curve.
