| danlan2 | Adjusted R^2 =1-(n-1)*SSE/((n-k-1)*SST) =1-17*30/(14*120)=39/56 =0.6964 |
| MasterD | Adjusted R^2 == Rbar^2 Rbar^2 = 1 - (n-1)/(n-k-1) * [1-R^2] Substitute R^2 = 1-SSE/SST you get Rbar^2 = 1 - (n-1)/(n-k-1) * [1-(1-SSE/SST)] = 1 - (n-1)/(n-k-1) * [SSE/SST] Rbar^2 = 1 - (n-1)/(n-k-1) * [SSE/SST] = 1 - (18-1)/(18-3-1) * [30/120] = 0.6964 |

I just wanted to share the good news that I passed CFA Level I!!! Thank you for your help - I think the online question bank helped cut the clutter and made a positive difference.
