Six World Series: Time Series Analysis and Forecasting

Details

For our October Data Science DC Meetup, we're talking about the World Series. No, not that World Series* -- time-series data about the world! Long-time DSDC attendee Lee De Cola will be showing how to think about, analyze, and forecast important world-wide metrics that have been collected for over 50 years. Expect to learn about rigorous ways to analyze temporal data. And maybe there'll be baseball puns.

  • Anybody want to talk about post-Moneyball sports analytics sometime? Get in touch!

Agenda:

• 6:30pm -- Networking, Empanadas, and Refreshments

• 7:00pm -- Introduction, Announcements

• 7:15pm -- Presentations and Discussion

• 8:30pm -- Data Drinks (Tonic, 2036 G St NW)

Abstract:

This presentation will use statistical and visualization features of R to explore yearly time series that characterize key global changes since 1950, a period sometimes called the Great Acceleration. Linear regression supplemented with autocorrelation diagnostics can provide most of the key descriptive information about these data, while nonlinear estimation and exponential smoothing can be used to provide forecasts. However, forecasting – in the sense of providing point predictions of future values – should be used descriptively and as providing warnings. Widespread understanding of these data is of surpassing importance to the future welfare of life on Earth.

Participants who would like to follow along are welcome to bring computers loaded with R and to download in advance (WiFi will not be available) the data used for this presentation at http://ldecola.net/projects/global/ .
