Hi, Jae. As mentioned at 0:17, those represent sums of squares. Different books might use varying symbols or notations, but the underlying formulas remain consistent. For instance, some books use SS(XY) with XY as a subscript. While the symbols may differ, it's crucial to focus on the shared formulas-they are the essence of the concept. Thanks for watching and have a nice day.
Hi there! Here's the video you requested: ruclips.net/video/OdToFRnUOKA/видео.html. I hope it's not too late-I had to renew my subscription before recording it. Hope this video helps you. Thanks for watching, and have a great day!
We do as : For Equation: a+b1x1+b2x2....we develop €Y=na+b1€x1+b2€x2 €x1y= a€x1+b1€x1²+b2€x1x2 €x2y= a€x2+b1€x1x2+b2€x2² (All the value from calculator) solve these 3 eqn from calculator to get A,b1 and b2.
It's a very complex one to solve on calc but shown easily thank you for the information 😊
My pleasure. Thanks for watching and have a nice day.
Is sum of xy not equal to sum of XY? Why do you need to substract sum of XY with sum of X * sum of Y / n?

sir do it on 991 es plus

We do as :
For Equation: a+b1x1+b2x2....we develop
€Y=na+b1€x1+b2€x2
€x1y= a€x1+b1€x1²+b2€x1x2
€x2y= a€x2+b1€x1x2+b2€x2²
(All the value from calculator) solve these 3 eqn from calculator to get A,b1 and b2.
So, which method do you prefer?
