Parameter: Regression degree


Full name: Polynomial degree for curvilinear regression
Range: [ 0, 20 ]
Initial value: 0

Affects: all graphs

Curvilinear regression can be performed on the data of any graph. This parameter can be set to the degree desired: 0 for no regression, 1 for linear regression, 2 for quadratic, etc. (up to 20). The regression line or curve will be drawn on the graph. A line above the graph will indicate the correlation coefficient (labelled as R2, actually R-squared), the intercept (b), and the slope coefficients (m).
