Question

Pleasee I need the correct and best full answer for this problem with explanation and Good Handwriting!

Problem: Deduct the formulas of the m and b coefficients from the best-fit line using calculation, i.e., minimize the sum of squares of the errors made by the fitting curve. It takes the derivative with respect to the coefficients and finds the critical point.

Thank You! I will rate this answer if is complete with critical point!

Answer 1

Solution Let, Assume the best fit line is, y = m+bx So, for Each point the line will have some Error and can be written as, Hi - mt boite where, €; if Egocen associated withits afb's E = (y; -m-bxi) & G = 8 (Yi-m-bx;) To minimise the Squared voor, we need to differenciate e f Witrit mib. So, Don & J (y; -m-ba;}? = 2CY: -m-647) * (-1)=0 Hi -mn- b ê ni 20 - - and

- 2 ( 41 -m-b4)(-4;)-0 - 414-m*: -62270 Solving en € 80, We can get and 9432 - to 24 mo m=y-
