Probit tepki fonksiyonu

probit.model <- glm(HOPPINESS ~ price.ratio,
                    family = binomial(link = probit), data  = choice.data)

coef(probit.model)

(Intercept)  price.ratio 
  -1.954092    -3.547546

cbind(coef(logistic.model), coef(probit.model))

                 [,1]      [,2]
(Intercept) -3.572678 -1.954092
price.ratio -6.738768 -3.547546

Yeniden ölçekleme
