| Yurik74 | That's a good one! |
| rhardin | C is just as correct as B, so why is the answer only B? I see the "most accurate" part of the question, but something is either accurate or its not, and C is accurate from what I can see. Right? |
| pikusa | SEE is not going to decrease with more observations if model is not correctly specified. So C is not always correct. B is just a rephrased definition of SEE. |
| chriswwu | good point, pikuse. very subtle. |
| JZERMENO | A little bit tricky... |
