This analysis evaluates the effectiveness of a time series model in forecasting taxi ridership. Typically ridership data is not available in a time series format, however, the data that is available (individual trips per month) can be aggregated and structured as a time series object. This analysis does just that by taking monthly ridership data produced by the City ranging from 2010 through 2018, aggregating the number of trips by month, and storing this as a time series object in R. An exploratory analysis is conducted inclusive of appropriate decomposition to identify a suitable model (ARIMA in this case). The data is then split into training (2010-2017) and test (2018) sets, modeled on the training data, tested on the testing data, etc. The final result includes necessary error/residual testing and charts for comparison, available here
