The full GLMM model for development rates included fixed factors of temperature, photoperiod, diet, larval rearing density, and a dummy variable of temperature variability (constant or variable temperature).
The dependent variable was a dummy variable of the current employment situation, which received the value of 1 if the individual worked last week and 0 otherwise.
The estimation results of this model, presented in Table 8, show that the coefficient of a dummy variable of company car owner is 8,483.
Finally, a dummy variable of the year of treatment was included in the model.
The significance of the difference in risk by time of cancer diagnosis was tested by including an interaction term as cross product between aspirin/ibuprofen and time of cancer diagnosis (as a dummy variable of first year vs later years).
We further included the frequency of involvement in eight leisure activities, and a dummy variable of whether the participant often does regular exercise (yes versus no).
Other than the key independent variable, we introduced a series of control variables such as GDP per capita, the ratio of urban population, total population, land-area size, and a dummy variable of county-level city (see Table 3).
Auditor type is a dummy variable of zero (0) and one (1) for local audit firms and the 'big four' public accounting firms operating in Ghana respectively.
A dummy variable of zero (0) is assigned to companies considered non-sensitive and one (1) assigned to environmentally sensitive firms.
Error reporting was recoded with a dummy variable of 0 = unfavorable error reporting culture and 1 = favorable error reporting culture.
