Quadratic regression is a type of multiple linear regression by which the equation of a parabola of 'best+fit' is found for a set of data. Draw a second degree polynomial with polynomial regression for the given data set.
A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
+y=ax%5E2%2Bbx%2Bc where a≠0 .
The best way to find this equation manually is by using the least squares method.
