Curvilinear Regression Coefficients

 

Use RECODE with REGRESSION to compute curvilinear regression coefficients. This type of curvilinear regression is also known as polynomial regression. Use RECODE to create the second order terms, e.g., R1 = V1*V1 and R2 = V1*V2, etc.

The appropriate statistical test for a significant relationship is the F test, computed by REGRESSION, which is also equal to t-squared, for each coefficient.
