Univariate Time Series with Stata
Learn about univariate timeseries analysis with an emphasis on the practical aspects most needed by practitioners and applied researchers. Written for a broad array of users, including economists, forecasters, financial analysts, managers, and anyone who wants to analyse timeseries data. Become expert in handling date and dateâ€“time data, timeseries operators, timeseries graphics, basic forecasting methods, ARIMA, ARMAX, and seasonal models.
We provide lesson material, detailed answers to the questions posted at the end of each lesson, and access to a discussion board on which you can post questions for other students and the course leader to answer.
