Problem: Demonstrate how to compute simple and multiple linear regression.
This will demonstrate your knowledge of identifying key elements in performing multiple linear regression.
In your company, find historical data about a major process that has been improved in the last five years. Identify 3-5 variables (predictors) that you think were "responsible" for the improvement, and identify a metric that summarizes the improvement metric (for example, performance or capability). Based on the data, perform multiple linear regression to explain which of these variables has the greatest potential to influence your dependent variable. Post the graph and comments.
