An In-Depth Guide to Least Squares
The method of least squares is a standard approach in regression analysis to approximate the solutions of overdetermined systems – sets of equations in which there are more equations than unknowns. At its core, least squares seeks to find the "best fit" line or curve for a set of data points by minimizing the sum of the squares of the "residuals," which are the differences between the observed values and the values predicted by the model. This technique is fundamental in data fitting and is widely used across various disciplines.
