Definition that contains regression
- rectilinear regression the relation between variables when the regression equation is linear: e.g., y = ax + b
- regression line a smooth curve fitted to the set of paired data in regression analysis; for linear regression the curve is a straight line
- linear regression the relation between variables when the regression equation is linear: e.g., y = ax + b
- regression analysis the use of regression to make quantitative predictions of one variable from the values of another
- multicollinearity a case of multiple regression in which the predictor variables are themselves highly correlated
- regression coefficient when the regression line is linear (y = ax + b) the regression coefficient is the constant (a) that represents the rate of change of one variable (y) as a function of changes in the other (x); it is the slope of the regression line
- predictor variable a variable that can be used to predict the value of another variable (as in statistical regression)
- regression curve a smooth curve fitted to the set of paired data in regression analysis; for linear regression the curve is a straight line
- curvilinear regression the relation between variables when the regression equation is nonlinear (quadratic or higher order)
