Method: Scipy.polyfit ( ) or numpy.polyfit ( ) This is a pretty general least squares polynomial fit function which accepts the data set and a polynomial function of any degree (specified by the user), and returns an array of coefficients that minimizes the squared error. A detailed description of the function is given here.

WebFeb 20, 2024 · These are the a and b values we were looking for in the linear function formula. 2.01467487 is the regression coefficient (the a value) and -3.9057602 is the intercept (the b value). So we finally got our equation that describes the fitted line. It is: y = 2.01467487 * x - 3.9057602.
