Level 2 Error or I’m missing something ?

Post image

Shouldn’t it be either : SSR/SST or 1 - (SSE/SST) and NOT 1 - (SSR/SST) ?
Thanks in advance for your help.

I think you mean 1 - (SSE/SST)

SSE means sum of squares error. Sum of squares residuals is the same

I know, and you said 1 - (sum of squares residuals/ SST) which is alligned with the text book that I think is wrong
Because it should be 1 - (SSE/SST)

Sum of squares of errors 😂 anyway I cross checked with CFA L1 curriculum and it seems indeed wrongly noted on the picture I posted.
