Hoorcollege
Stap 5. Evaluatie statistische fit én praktische relevantie van het model
• Gehele model
• Individuele predictoren
Goodness of fit:
R2 als de maat voor algehele modelfit
R2 = determinatiecoëfficient
R2 =
R2 = percentage variantie verklaar door het model
Kwadratensom/sum of squares (SS)
SST = total SS: totale kwadratensom
SSM = model SS: kwadratensom van het model
SSR = residual SS: kwadratensom van de voorspellingsfout
Totale kwadratensom (SST)
Som van de gekwadrateerde afwijkingen van geobserveerde scores tot het algemeen gemiddelde
Kwadratensom van het model (SSM)
Som van de gekwadrateerde afwijkingen van voorspelde scores tot het algemeen gemiddelde.
,Kwadratensom van de errors (SSR)
Som van de gekwadrateerde afwijkingen van de geobserveerde scores tot de voorspelde scores.
, Alle predictoren samen verklaren 13.7%.
Om predictoren met elkaar te vergelijken gebruik je de gestandadiseerde Beta.
Je gebruikt dus voor de regressie vergelijking de gewone B.
