The problem of multicolinearity is a persistent one, usually bringing devestation with it for analysts unable to detect/treat it. Perform a preliminary search of cases in which multicolinearity presents an issue for researchers/analysts, and explain potential sources of the multicolinearity (using rigorous reasons discussed in chapter 9.3).
Now consider the patient-satisfaction data from the Topic 2 assignment. Analyze this data for near-linear dependence by using Equation 9.3 to compute the variance inflation factor. Does this data exhibit multicollinearity?
