Multiple R

Represents a measure of the correlation between observed and predicted values of a variable in multiple regression analysis, indicating the strength and direction of a linear relationship.

Autocorrelation

A measure of how correlated a variable is with itself over successive time intervals, often used in time series analysis.

Significance F
