What you're trying to do is called model selection. You may find a popular library method for this, but it's important you know how the model is selected, even if it means writing a little code yourself. The basic idea is to take a measure of fit quality, then penalise by a measure of model complexity. marriage certificate in floridaWebApr 2, 2024 · Least Square Criteria for Best Fit. The process of fitting the best-fit line is called linear regression. The idea behind finding the best-fit line is based on the assumption that the data are scattered about a straight line.
