Table 5 presents the parameter estimates from the ordered probit model of consumer choice
for organic and integrated fruit and vegetables in Slovenia.
Based on the results of a likelihood ratio test (Pindyck and Rubinfeld, 1991) the model is
statistically significant at 99% or above. The results of the χ2 test reveal that the differences
between the model coefficients are statistically significant. However, the value of the
likelihood ratio index (LRI) goodness-of-fit coefficient (Greene, 1997) is rather low (0.049),
which implies that the model explains only a part of the variance within the dataset. However,
the main purpose of this empirical work was not to maximise probability function but to
evaluate impact of some attitudinal variables on purchase frequency. Rather low LRI values
were also expected due to the fact the survey dataset comprised only rather general
determinants influencing households' purchasing behaviour. For higher degree of explanatory
capacity of the model clearer definition of determinants is needed in the future work.
