One key distinction between regression models in econometrics and supervised learning methods in machine learning is the type of model being fit to the data. Time series analysis is a way of analyzing a sequence of data points collected over an interval of time. In economic statistics, the empirical data is collected recorded, tabulated and used in describing the pattern in their development over time. However, the true coe¢ cient is actually identi ed from the data, using an idea analogous to the panel data case above [Kane, Rouse, and Staiger (1999)].
