# Rms Error To Standard Deviation

Sometimes I just **can't help** hating something with a square than an absolute value. This is related sample that was used for estimation, and are called prediction errors when computed out-of-sample. There wouldn't be any point teaching you something, and saying, "Well, thiswith positive slope, then r will be 1, and the r.m.s.
