NettetEngineering; Computer Science; Computer Science questions and answers; Problem 2: The Method of Least Squares (also known as line of best fit/linear regression)Part I: The method of least squares is used extensively in physics and engineering experiments where measurements of n-pairs (𝑥𝑖 , 𝑦𝑖 ) of two physical quantities are observed. Nettet31. okt. 2024 · $\begingroup$ Linear least squares regression problems -- even those with elaborate basis expansions and interaction terms -- can be solved efficiently in closed form (iterative solutions are unnecessary), and this is also the case for least squares solutions with quadratic penalties on the coefficients (such as ridge regression or the ...

NettetLeast squares linear regression, as a means of finding a good rough linear fit to a set of points was performed by Legendre (1805) and Gauss (1809) for the prediction of planetary movement. Quetelet was responsible for making the procedure well-known and for using it extensively in the social sciences.
