WebThis paper deals with the numerical calculation method of deflection deformation of rice stalks. Due to large deflection of rice stalks caused by reel operation, it is improper to adopt the conventional formula that is usually used in small deflection calculation to fit rice stalk deformation curves. Therefore, a large deflection calculation formula in combination with … WebCurve Fitting with Log Functions in Linear Regression. A log transformation allows linear models to fit curves that are otherwise possible only with nonlinear regression. For instance, you can express the nonlinear function: Y=e B0 X 1B1 X 2B2. In the linear form: Ln Y = B 0 + B 1 lnX 1 + B 2 lnX 2.

If a function of the form cannot be postulated, one can still try to fit a plane curve. Other types of curves, such as conic sections (circular, elliptical, parabolic, and hyperbolic arcs) or trigonometric functions (such as sine and cosine), may also be used, in certain cases. For example, trajectories of objects under the influence of gravity follow a parabolic path, when air resistance is ignored.
