Talk:Residual mean square

WRSS
What is WRSS? Woodlands Ring Secondary School? I guess it stands for "weighted residual sum of squares", but how should the reader know this? Also, in statistics RMS conventionally means Root mean square, which is more-or-less the square root of the quantity defined here, so this can get confusing. This paragraph is in urgent need of a home in which it can be embedded. --Lambiam 03:51, 23 August 2007 (UTC)
