| danlan2 | Using PSA benchmark, CPR = 6%*t/30 When PSA=90, CPR=0.9*0.06*10/30=1.8% |
| pb09 | where'd we get 6% and 10/30 from?? |
| bodduna | If t<30, cpr = 6%*t/30, If t>30, cpr = 6%. It is a standard |
| Catalin92 | This came from nowhere... |
| khalifa92 | yeah and there's no emphasize about it in the book. just 3 lines. |
| Ewan2015 | odduna: Thank you for explaining that. Better than the summary that makes no mention of that standard :( |
I am happy to say that I passed! Your study notes certainly helped prepare me for what was the most difficult exam I had ever taken.
