Linear Algebra: Ch 2 - Determinants (48 of 48) Method of Least Squares

In this video I will use the method of the least squares and matrices to find the equation of the line that best fit a set of data points.

First video in this series can be seen at:

Dear Dr Michel van Biezen
I just finished watching these 48 videos today. You are a great teacher and i am very grateful for your help. I live in switzerland and my teachers in physics and maths are awful so i started watching your videos and it helped so much. I learnt more from your videos than in this whole school year so far. Thank you sir! I would give anything to have you as my teacher!

Hi Dr van Biezen, Just wanted to say thank you so much, I just managed to top the class in Physics II, and I learnt pretty much all of it from watching your videos! Thanks again for making resources like this avaliable to the public!

I've always been scared of maths until I found you Michel, you make everything so simple to understand, great teacher. Thanks for all your efforts, it's very appreciated. Adam from Scotland.

You blow my mind with this grand finale :-o

Great teacher indeed. Please extend this topic to ordinary least squares, partial least squares and weighted least squares.

Thank you so much, I was looking for this! Great explanation

I find this pretty neat how it follows Crammer's rule
