Decision makers require rigorous support from extensive data analysis. This course provides you with several tools to prepare, analyze, and present the results of data analysis. These tools cover topics in data design and visualization, exploratory data mining and basic machine learning, probability, sampling and statistical inference, traditional and robust regression, Monte Carlo simulation and bootstrapping, and decision optimization. Tools will be built in Excel and R, an open source programming language in wide use. They will be applied across an organization’s value chain to problems of inventory, market share, pricing, budgeting and forecasting, and risk management, among other topics.
