Varianties van het regressiemodel
- Totale variantie (MSy) = SStotaal : dftotaal = SSy : dfy
Waarbij:
SSy = (y - y )2
dfy = N -1
- Model variantie (MS ^y ) = SSmodel : dfmodel = SS ^y : df ^y
Waarbij:
SS ^y = ( ^y - y )2
df ^y = p (aantal predictoren)
- Residuele/error/onverklaarde variantie (MSe) = SSerror : dferror = SSe :
dfe
Waarbij:
SSe = (y- ^y )2 dit is ook wel de som van ei in het kwadraat
dfe = N-p-1
