In this study, the levels of Y range from 0 – 100%, with an increment of 10%.
The dummy variables D1 and D2 have values of either 0 or 1. The levels of X1 range
from 1 time – 11 times, with an increment of 1 time. The levels of variables X2-X610
range from 0 – 100%, with an increment of 10%. Table 2 shows selected results of the
marginal effects from the study. The authors try to select the results which show that
they are statistically significant at the highest confidence interval (99%) and also have
the highest positive coefficient value. In most model types, when level of Y equals
80%, it gives the highest confidence interval and also positive coefficient value.
