Summary

This chapter introduced time series analysis by reading in and exploring Health Care Enrollment Data from the CMS website. Then we moved on to defining some basic Time Series concepts such as Simple and Exponential Moving Averages. Finally we worked with the R “forecast” package to work with some exponential smoothed state space models, and showed you one way to produce automated forecasts for your data. We also showed various plotting methods using the ggplot, lattice package, as well as native R graphics.
