polychotomous variable demonstrating off-farm activity type participation;
As a first step a
polychotomous variable ranging from one to four was constructed where "1" showed the minimum vaccination while "4" shows complete vaccination against all diseases.
This sophisticated method has become increasingly useful in empirical studies to counter selection bias problems with
polychotomous choices (e.g.
As a predictive analysis, multinomial logistic regression is appropriate for this study because it describes the relationship between a
polychotomous dependent nominal variable and a mixture of continuous and binary independent variables (Liao, 1994).
The decision whether to move uses a logistic regression, while the location decision uses a conditional logit (
polychotomous).
In a situation where the dependent variable is
polychotomous and ordered, dichotomous regression models such as LPM, binary probit, or binary logit models are inappropriate.
They also argue that
polychotomous scales generates smaller but more errors, while dichotomous scales generates larger but fewer of them.
A total of 90 telephone questionnaires were conducted using multiple-choice questions and
polychotomous responses, where the person being questioned is asked to select one or more options.
Quarter 1 served as the reference category for the seasonal
polychotomous dummy variable.
