About the Talk:
Data scientists and researchers are often tasked with measuring how a metric changes over time. Whether it's daily website visits, weekly sales, monthly unemployment rate, or annual population count, time series is one of the most commonly analyzed data formats across fields. This talk will demonstrate two statistical methods for approaching times series analysis, forecasting and anomaly detection, and when to apply them.

While forecasting allows us to predict future trends, anomaly detection helps us uncover irregularities in our data. We will draw upon real-life examples to explore different anomaly detection algorithms and illustrate how forecasting can help us identify seasonal trends and set targets for the future.

I will be introducing the following packages in R: Facebook's open-source forecasting package, prophet, Twitter's open-source AnomalyDetection, and its tidyverse counterpart, anomalize. Prior experience is not necessary and people of all levels are encouraged to attend.
