Hi,
I am going to model the farmer behavior to find how he reacts to some factors. I found that I should use descriptive decision model based on questionnaires. But I don't know how to validate the accuracy of the proposed model? For example I want to model how farmers make decision about time of irrigation. how can I find the accuracy of the model? I think ti's not possible to watch some farmers and record their irrigation time. Besides it's not possible to find the irrigation time based on groundwater table fluctuation.
Well,
Plant irrigation depends primarily on the water of the soil moisture zone , which is a part of the unsaturated zone while the groundwater level represents the upper surface of the saturated zone . Therefore, a model procedure for irrigation through the fluctuation of the groundwater level is very far from the possibility of linking it to irrigation.
Sincerely
You might want to consider Logistic/ Probit Regression or similar methods for your problem.
Logistic regression may help to solve your research question. Regards,
