The Cubic Regression app computes the Cubic equation and computed (x,y) data points.
The Data Entry Screen for the Cubic Regression App has two data entry fields for the x: and y: data points
The app computes the Cubic Regression equation and computed (x,y) data points.the linear regression equation has an equation of the form y = ax3 + bx2 + cx + d where X is the explanatory variable and Y is the dependent variable. .
The app has a touch enabled graph. Upon touching the graph a vertical line appears. Move the vertical line to the left or right to display the computed (x,y) data pairs.
