Sir in the matrix multiplication of (XtX)-1(Xt) we are getting some values in the resultant matrix different from your answer sir

How to calculate inverse?

[@PixelsbyMeebs]

Have you figured it out or do you still need help?

[@remassh1350]

@@PixelsbyMeebs can you help me how calculated ?

[@PixelsbyMeebs]

@@remassh1350 Of course!!! (The method might seem lengthy but BELIEVE ME IT'S REALLY EASY!!!) In order to calculate inverse you should/can use calculator. If you're using Casio fx-991Es Plus calculator then the method to calculate inverse is: • Press Mod button. • Select "Matrix" option by pressing 6. • Choose "Matrix A". • Select the matrix size you want to take inverse of. (For example: 2×2, 2×1, 3×3 or any matrix you) • Store the values inside your matrix. • Now that you're done storing them press "AC". • Press "Shift" and then press "4" (for Matrix options. • Now you'll see different options. Choose Matrix A. (In which you had stored the values earlier) •Matrix A is what you'd be seeing on the screen. Now press "x-¹" (The button under the Mod button) •Press "=" and you're done!!!! (I am sorry if I missed any step. manual method would've been time consuming. This is an easy and quick method. ) :')

can i know y the first colomn is always biased?

[@trushti_1375]

Look at the polynomial equation It's y = a0 + a1x1 + a2x2.... So from this we notice that x0 = 1 ... That is the reason we keep series of 1s in the matrix because it is basically representing coefficient of a0.

[@mohithsuhas8007]

​@@trushti_1375yeah I didn't think of that. thank you for the explanation!

It's because base unit of all numbers is one. It's either it's scaled up or down or subtracted or added. E.g 1unit*20 =20units.
