error field contains the standard error of the intercept. The Intercept field contains the intercept value if you selected to include the intercept in the model on the The Standard error of estimate measures the dispersion of the observed values about the regression line. It is adjusted by dividing the error sum of squares and total sums of square by their respective degrees of freedom. The Adjusted R2 is interpreted similarly to the R2 value except the adjusted R2 takes into consideration the number of degrees of freedom. of cases field contains the minimum valid sample size (N) depending on the MD Deletion option that you selected.Īdjusted R2. Residual SS is the error sums of squares and the Total SS is the total sums of squares.

The R2 (R-square) field contains the coefficient of multiple determination, which measures the reduction in the total variation of the dependent variable due to the (multiple) independent variables. Here:į = Regression Mean Square/Residual Mean Square. The F-value, df, and resulting p-value is used as an overall F-test of the relationship between the dependent variable and the set in independent variables. This statistic is useful in multivariate regression (i.e., multiple independent variables) when you want to describe the relationship between the variables. The Multiple R field contains the coefficient of multiple correlation, which is the positive square root of R-square (the coefficient of multiple determination, see Residual variance and R-square).
