The purpose of this project is to develop time series models to investigate prescribing practices and patient usage of medications with respect to the severity of the patient condition. The cost of medications is rising from year to year; some medications are prescribed more often compared to others even if they have similar properties. It would be of interest to pharmaceutical companies to know the reason for this. In this case, we predict the cost of medications, private insurance payments, Medicaid payments, Medicare payments, the quantity of medications, total payment and to study why the cost is rising in one medication compared to others. We investigate how much patients are spending on average for their prescriptions of medications, taking the inflation rate into account as a time-dependent regressor. Both forecasts, the one that incorporates the inflation rates and the one that does not are compared.
