Case Study #3 is intended to test your knowledge of how to run and interpret nonlinear regression models.

A recently released government report suggests that the number of new construction housing starts nationwide is influenced by mortgage rate volatility. A local home builder is interested in creating a model for predicting the number of housing starts within his geographic region using the prevailing mortgage rate as a potential predictor variable. The information in file pertains to a random sample of monthly housing starts in the particular geographic areas of interest over a five-year period.

Using the data file, calculate and interpret the various nonlinear regression models required in the instruction sheet.
