เรียนรู้วิธีคาดการณ์โดยใช้การถดถอยเชิงเส้นอย่างง่าย ในการทำเช่นนี้ คุณต้องใช้ฟังก์ชันการถดถอยเชิงเส้น (y = a + bx) โดยที่ “y” เป็นตัวแปรตาม “a” คือจุดตัด y “b” คือความชันของเส้นถดถอย และ “x” . เป็นตัวแปรอิสระ วิดีโอนี้ยังแสดงให้คุณเห็นถึงวิธีการกำหนดความชัน (b) ของเส้นถดถอย และการสกัดกั้น y (a) ในการหาความชันของเส้น คุณจะต้องหาค่าสัมประสิทธิ์สหสัมพันธ์แบบเพียร์สันก่อน ซึ่งอธิบายไว้ในวิดีโอแยกต่างหาก ( .

Very good explanation. However, I just want to point a mistake in the last operation for Y when Mr. O'Loughlin adds 30.133 instead of 30.123

b cap you can directly calculate with formule = Sum of (x-xmean)(y-ymean)/sum of (x-xmean)square

A very interesting video no doubt and the Irish accent is a great addition, especially if you are going to watch it 7 times, almost one after the other as I did … I understand the importance of the PCC to find relationship between X and y (if any) but when it comes to the slope, why are you not calculating it as the result of SP / SSx, especially when we have those values good and ready?

How would you transform the linear regression into a logarithmic regresssion?

I had a case where the value of a using the regression line intersection with y axis is different than the value i calculated, why is that?

the excel calculated a of 9949
but the regression line intersection is 12500

I wish my Computational Mathematics teacher would have half the teaching skils that Dr. Eugene has. This was the best linear regression class I have ever had and I enjoyed every second. Thankyou Dr. Eugene.

typical Irish teachers, they are going to tell you your attitude according to their incompetent map of the world because they have been appointed by God.

May I ask you that why x=15? And what the meaning of figure x? If the question did not give out the figure x how do I work out the final result?

James Laforteza 16/10/2021 - 6:31 PM

I have a question where did you get the value of x?
