If d = 0, we obtain quadratic regression; and If c = d = 0, then we get a simple linear regression model. And that's it when it comes to the cubic regression equation! The main challenge now is to determine the actual values of the four coefficients. To find the coefficients of th...
Cubic regression is a process that generates a third-degree equation that fits a given set of data. Cubic regression is part of a family of regression techniques known as polynomial regression. We often use the cubic equation when a given dataset follows a cubic curve. If we want to find t...

They cover the Cubic regression equation, the Quadratic and Linear regression equations(for reference only). Cubic regression equation function has th...
or, using the notation from our cubic equation calculator: ax3+bx2+cx+d=0.ax3+bx2+cx+d=0. Cubic equations appear in many different areas of maths and science. For instance: The characteristic polynomials of a 3×3 matrix are the roots of a cubic polynomial. Cubic regression is a stati...

In this article, I will go through cubic splines and show how they are more robust than high degree linear regression models. First I will walk through the mathematics behind cubic splines, then I…
Regression analysis to estimate binary interaction parameters has been done by using an improved version of the "fugacity criterion" of Pauvonic et al. Also comparison with several other cubic equations of state has been done. In all cases the proposed equation works better....
