Fitting a Line using Least Squares #SoME2

This video tutorial explains the least squares method, a powerful tool for fitting data to a line. It begins with an intuitive approach to finding the best fit line and progresses to a mathematical definition involving error minimization. The tutorial then extends the concept to a more general line with two parameters, using linear algebra and multivariable calculus. The video is designed to be accessible to those with basic calculus knowledge, while also offering deeper insights for advanced learners.
