I am doing my masters, majoring in Data Analysis. The research paper I want to get done is based on a course called decision making under uncertainty. Over the span in this course, we have learnt about various tools that can be used to make decisions under times of uncertainty. Tools like decision tree, monte carlo simulation etc. The research paper is based around three tools, decision tree, scenario planning and monte carlo simulation. starting from their history, when they were first used to their current use. The paper also should also discuss a particular current issue in the country of United States, for this paper the issue is related to Medicaid expansion in a certain state. Ideally the situation is to be assessed from the point of view of The Governor and recommendations are to be made in regards to which tool will be most ideal for reaching a decision.
