A Time-Series analysis and forecasting of different Open Online Course Participants around the globe for years 2012-2016 using R. This stochastic time-series graph was obtained from a rich data of over 640K unique users.
It can be observed that "computer science" remained to be favorite among the participants throughout, and incredibly reached a peak of 300K in late 2014.
The figure above shows the prediction attained by participants in STEM courses for the following 12 months. This prediction is achieved using ARIMA model in R, that predicts a slight rise of participants in early months of 2017.
All thanks to HarvardX and MITx for the awesome data!
