The coefficient estimates given in Table 2 can be interpreted in the following ways. The coefficient estimate for “3 Buffets,” for example, indicates that the observed average food waste (grams) is 5.954 g higher if three instead of two buffets are set up while all other variables are kept at the same level. The coefficient for “Austria” indicates that if the percentage of Austrians staying at the hotel is 1 percentage point higher, the average food waste observed is 0.1 g lower. The estimate for “Younger guests” indicates that on days when the guest mix includes more young guests, the average food waste is 3.4 g higher compared with days when the share of older guests is higher. The standardized coefficients in Table 2 indicate that the importance of the coefficients for variables measured in percentage is in fact higher than their
