If there is any interest, I will post a summary of the responses to the list. I am looking for sets of time series data on the internet that I can use for student forecasting projects. I need to be able to obtain at least 40 different data sets each semester extending over the same time horizon and bucketed in the same manner. The data must be free of charge. It is nice from a teaching standpoint if the data has seasonality, trends and a few unusual points.
Nonseasonal cycles are also desirable.
