Typos in Pgs 15/16/17 - P1.T2. - S & W - Study Notes - Reading 11

[Dr. Jayanthi Sankaran]

Hi David/Nicole,

There are a couple of typos on Page 15/16/17 of the above:

We can break the regression equation into three parts:

Page 15

• Explained sum of squares (ESS)
• Sum of squared residuals (RSS) - it is (SSR)

Page 16

SER = SQRT(?SSR/n - 2) = SQRT(sigma ei(square)/ n - 2)

Page 17

ESS, RSS - it is ESS, SSR

Thanks!
Jayanthi

Jayanti
Page 16 SQRT(?SSR/n-2) i think ? Should not come its right to saySQRT(SSR/n-2) because SSR=sigma(ei(square))
And yes RSS should be replaced with SSR.
Thanks

Yes, page 16 corrections are not typos, because as Shakti points out SSR=sigma(ei(square)). Hence, it is right to say,

SER = SQRT(SSR/n - 2) = SQRT(ei(square)/ n - 2)

Sorry about that David/Nicole - my mistake. However typos on page 15 and page 17 stand!

Thanks
Jayanthi
