WitrynaA log transformation is a relatively common method that allows linear regression to perform curve fitting that would otherwise only be possible in nonlinear regression. For example, the nonlinear function: Y=e B0 X 1B1 X 2B2. can be expressed in linear form of: Ln Y = B 0 + B 1 lnX 1 + B 2 lnX 2. show djongaWitrynaCurve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that approximately fits the data.

But since the system is over-determined, you need to use the left pseudo inverse: A + = ( A T A) − 1 A T. So the answer is: [ a b] = ( A T A) − 1 A T B Here is some simple Python code with an example: show dmesg
