How to find line of best fit.

Thank you @Philq02! That would be very helpful if I wanted to find the best fit of a linear model. Sadly, I want the best fit in general; and it looks like the best fit contains a division (e.g. a/X + b * X where a * b would need to be estimated). Hey - this gives me an idea - maybe I can use OLS and provide 1/X as one of the predictors.Least Squares Fitting. A mathematical procedure for finding the best-fitting curve to a given set of points by minimizing the sum of the squares of the offsets ("the residuals") of the points from the curve. The sum of the squares of the offsets is used instead of the offset absolute values because this allows the residuals to be treated as a ...In this activity, students visualize a line to fit a data set, then graph that line with sliders, and use it to make a prediction. Teachers can use the final screen to introduce the concept of the residual.Learn how to approximate a linear function that fits a given set of data points by sketching a line, using a graphing utility, or applying a formula. Also, understand the difference …In regression analysis, curve fitting is the process of specifying the model that provides the best fit to the specific curves in your dataset.
