-
multivariate analysis
a generic term for any statistical technique used to analyze data from more than one variable
-
regression, regression toward the mean, simple regression, statistical regression
the relation between selected values of x and observed values of y (from which the most probable value of y can be predicted for any value of x)
-
multiple correlation, multiple regression
a statistical technique that predicts values of one variable on the basis of two or more other variables
-
regression analysis
the use of regression to make quantitative predictions of one variable from the values of another
-
linear regression, rectilinear regression
the relation between variables when the regression equation is linear: e.g., y = ax + b
-
curvilinear regression
the relation between variables when the regression equation is nonlinear (quadratic or higher order)
-
correlational analysis
the use of statistical correlation to evaluate the strength of the relations between variables
-
ANOVA, analysis of variance
a statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables
