RMSE vs SEE

CFA Level II
#1

This has been discussed before, but I can’t keep anything in my head for more than 6-8 hours. What is the difference between the two? RMSE=square root of the average squared error SEE=square root of MSE MSE=SSE/n-(k+1)

That explanation doesn’t look right to me. Anyone else?

#4

Looks right to me, I remember RMSE being the out of sample SEE.

If that is the case then schweser does a pretty horrible job of explaning it. So they calculation is the same then? That is what I was getting at…
