5 dni temu · Let x be the explanatory variable and y the response variable. The aim of quadratic regression is to find an equation in the form: y = a + bx + cx²,. that best fits our data points (x 1, y 1), ..., (x n, y n).. In the case of c = 0, the model boils down to a simple linear regression.. To compute the coefficients of the quadratic regression equation, we usually use the least-squares method.
